What is passwordless authentication?
Passwordless authentication is any sign-in method that proves who you are without typing a shared secret. Instead of a password, the user unlocks something they have (a phone, laptop or security key) with something they are or know (a fingerprint, face scan or local PIN).
In business, the term usually means passkeys built on the FIDO2 standards. The FIDO Alliance defines passkeys as “FIDO cryptographic credentials that are tied to a user’s account on a website or application.” They can live on a phone, a computer or a hardware security key.
Not every “passwordless” product is equally strong. A magic link emailed to a user is passwordless, but it is not phishing-resistant.
How do passkeys and FIDO2 work?
FIDO2 is the FIDO Alliance’s family of sign-in standards, and WebAuthn is the part browsers and websites use; CISA refers to them together as FIDO/WebAuthn. In the FIDO Alliance’s words, “passkeys replace passwords with cryptographic key pairs.”
When an employee registers, their device creates a private key that stays on the device and a public key that the service stores. At sign-in, the service sends a challenge, the device signs it after a local fingerprint or PIN check, and the service verifies the signature with the public key. The FIDO Alliance notes that biometric data stays on the device and that there is no shared secret for attackers to steal from a server breach.
Synced vs. device-bound passkeys
The FIDO Alliance says passkeys “can be securely synced across a user’s devices, or bound to a particular device.” Synced passkeys (Apple iCloud Keychain, Google Password Manager) travel through a cloud account. Device-bound passkeys stay on one device, such as a YubiKey or Microsoft Authenticator.
Microsoft’s guidance is practical: treat synced passkeys as phishing-resistant but unattested, and use FIDO2 security keys “for highly regulated industries or users with elevated privileges.” NIST SP 800-63B-4 makes the same split: syncable authenticators are allowed at AAL2 but “SHALL NOT be used at AAL3.”
Why passwords and basic MFA are not enough
The FIDO Alliance cites Verizon data that 77% of hacking-related breaches involve stolen credentials. Adding MFA helps, but CISA’s fact sheet on phishing-resistant MFA shows that common second factors still fail:
- SMS and voice codes are exposed to phishing, SS7 attacks and SIM swaps. CISA says SMS “should only be used as a last resort.”
- Push without number matching is open to push bombing, where attackers spam prompts until a tired user taps Approve.
- App or token one-time codes can be typed into a fake login page and replayed.
CISA states that “the only widely available phishing-resistant authentication is FIDO/WebAuthn.” It also stresses that “any MFA is better than no MFA,” and suggests number matching as a stopgap for small and midsize businesses that cannot move to FIDO right away.
Passwordless methods compared
The table below compares the five methods small businesses usually consider. Phishing resistance is based on CISA and NIST definitions.
| Method | How the user signs in | Phishing-resistant? | Typical cost | Best for |
|---|---|---|---|---|
| Synced passkeys | Face, fingerprint or PIN on phone or laptop | Yes (unattested) | Usually included in your identity provider | Most staff |
| FIDO2 security keys | Tap or insert a key, plus PIN or touch | Yes (device-bound, strongest) | $29–$98 per key at the Yubico store | Admins, finance, shared devices |
| Windows Hello for Business | PIN or biometric on a Windows PC, key held by the TPM | Yes, per Microsoft | Included with Windows Pro/Enterprise entitlements | Microsoft-based offices |
| Push approval in an app | Approve a prompt on a phone | No (number matching reduces push bombing) | Included in most MFA plans | Interim step |
| Magic links / email codes | Click a link sent to email | No; only as strong as the mailbox | Low | Low-risk customer apps, not staff |
Windows Hello for Business in brief
Microsoft describes Windows Hello for Business as key- or certificate-based authentication with “no symmetric secret (password) which can be stolen from a server or phished from a user.” The private key is protected by the device’s TPM, and the PIN never leaves the device. Licensing entitlements come with Windows Pro, Enterprise E3/E5 and Education editions. It does not work with Microsoft Entra Domain Services.
Best passwordless authentication tools and pricing
For a 10–50 person company, the right tool is usually the identity provider you already use. Prices below are from each vendor’s own page.
Microsoft Entra ID (with Microsoft 365)
Microsoft says passkeys (FIDO2) “are available in all Microsoft Entra ID editions, including Microsoft Entra ID Free. No extra licenses are required.” Supported options include FIDO2 security keys, Microsoft Authenticator passkeys and synced passkeys. Admins can enforce attestation and restrict allowed key models by AAGUID.
The catch is policy. Conditional Access, which lets you require phishing-resistant sign-in for admins or risky apps, needs Entra ID P1. Entra pricing lists P1 at $6 and P2 at $9 per user/month, with Entra Suite at $12. Microsoft 365 Business Premium ($32 per user/month with Copilot, paid yearly) includes advanced Entra identity features, and Microsoft Learn confirms Business Premium customers can use Conditional Access.
Choose it if you run Microsoft 365 or Windows. Skip it if your company lives in Google Workspace and has no Microsoft licenses.
Google Workspace passkeys
Google Workspace admins can turn on “Skip passwords” under Security > Authentication > Passwordless in the Admin console, per Google’s help center. Users then create a passkey on a phone, computer or security key. Admins can also restrict passkeys to hardware security keys only.
Two caveats from Google’s own page: turning it on “doesn’t deactivate or remove the user’s existing password,” and enrolling a passkey “doesn’t automatically turn on 2SV.” Workspace pricing showed Business Starter at $7, Standard at $14 and Plus at $22 per user/month on flexible billing.
Choose it if Google Workspace is your main login. Skip it if you need device-level conditional access on lower tiers; Google lists context-aware access under Enterprise.
Okta Workforce Identity
Okta lists Starter at $6, Core Essentials at $14 and Essentials at $17 per user/month, billed annually, with Professional and Enterprise by quote. There is a $1,500 annual contract minimum. Okta FastPass is positioned as a passwordless, phishing-resistant sign-in using device trust and biometric checks. The pricing page does not say which plans include FastPass, so ask sales.
Choose it if you have many SaaS apps and want one SSO layer. Skip it if you have under 20 users and the $1,500 minimum is more than you would otherwise spend.
Cisco Duo
Duo lists Free ($0, up to 10 users), Essentials ($3), Advantage ($6) and Premier ($9) per user/month. Its pricing page lists “complete passwordless authentication” from Essentials up, while risk-based authentication starts at Advantage. Under 100 users, licenses are sold in increments of 10.
Choose it if you want low-cost passwordless authentication and MFA from a vendor that is not your email provider, at a published per-user price. Skip it if you only need it for Microsoft 365, where Entra may already cover you.
JumpCloud
JumpCloud’s SSO package is $11 per user/month annually ($13 monthly), and passwordless (JumpCloud Go) is a $5 add-on ($6 monthly). Conditional access is a $3 add-on or part of Platform Prime. There is no permanent free tier, only a 30-day trial.
Choose it if you want device management and identity in one console. Skip it if you only need passkeys for one or two apps.
YubiKey security keys
The Yubico store lists the Security Key NFC and Security Key C NFC at $29, the YubiKey 5 NFC and 5C NFC at $58, the 5Ci at $85, and the Bio FIDO Edition at $98. For passkey sign-in with Entra, Google, Okta or Duo, the lower-cost FIDO Security Key line is a reasonable default; check Yubico’s spec sheet if you also need older protocols.
Pros
- Device-bound, so the key cannot be copied to a cloud account
- Works across Entra, Google, Okta and Duo
- No phone needed, which helps on shop floors and shared PCs
Cons
- Keys get lost, so every user needs a backup plan
- Hardware cost and shipping for remote staff
How much does passwordless authentication cost for 10 users?
Here is a worked first-year example for a 10-person US office, using list prices from the pages above.
| Setup | Software (year one) | Hardware | Total |
|---|---|---|---|
| Entra ID P1 + synced passkeys + 12 Security Key NFC (10 users, 2 admin spares) | 10 × $6 × 12 = $720 | 12 × $29 = $348 | $1,068 |
| Duo Essentials + 12 Security Key NFC | 10 × $3 × 12 = $360 | $348 | $708 |
| Okta Starter (annual minimum applies) | 10 × $6 × 12 = $720, but $1,500 minimum | $348 | $1,848 |
| JumpCloud SSO + Go add-on (annual) | 10 × ($11 + $5) × 12 = $1,920 | $348 | $2,268 |
If you already pay for Microsoft 365 Business Premium, the passkey side of passwordless authentication may add only the cost of security keys. The same is true for Google Workspace if you skip Enterprise-only controls.
Passwordless authentication rollout plan for a 10–50 person business
This plan follows CISA’s advice to start with high-value users and services that already support FIDO, then expand in phases. The week numbers are our suggested pacing, not a vendor requirement.
- Week 1: Inventory. List the systems to protect first: email, file storage, remote access, payroll and banking. Note which apps sign in through your identity provider and which still use their own passwords.
- Week 1: Pick the owner and policy. Decide who can register passkeys, whether to enforce attestation, and which roles must use device-bound keys.
- Week 2: Pilot with admins. Give IT and finance admins two security keys each (one primary, one stored safely). CISA recommends starting with help desk and IT admins.
- Weeks 3–4: Staff enrollment. Turn on passkeys for everyone.
- Week 4: Set recovery. Write down how a user who loses a phone or key gets back in, who verifies their identity, and how temporary access is issued.
- Weeks 5–6: Enforce. Use Conditional Access or your provider’s policy to require phishing-resistant sign-in for admins and sensitive apps. Remove SMS where you can.
- Ongoing: Close gaps. Put legacy apps behind SSO or replace them, and review sign-in reports monthly.
Passwordless authentication works best alongside a business password manager for the apps that still need passwords. See our guide to the best password manager for small business.
How to choose a passwordless authentication setup
- Already on Microsoft 365 Business Premium or Google Workspace? Start there.
- Do you need policies that force phishing-resistant sign-in for admins? Budget for Entra ID P1, Duo or an Okta plan that includes it.
- Will anyone sign in on shared or phone-free devices? Plan on FIDO2 security keys.
- Are you in a regulated field or handling federal data? Prefer device-bound keys with attestation.
- Do you have VPNs, desktop logins or on-site servers? Ask the vendor whether they are covered, not just web apps.
- Is there a written recovery process for lost devices?
Common passwordless authentication mistakes
- Leaving the password in place forever. Google notes that enabling passkeys does not remove existing passwords. Plan when fallback passwords and SMS will go.
- One key per admin. Lost keys lock people out. Buy two for every privileged account.
- Calling push “phishing-resistant.” CISA does not. Use number matching only as a bridge.
- Weak recovery. If anyone who calls the help desk can reset a passkey, attackers will call the help desk.
- Changing key restrictions carelessly. Microsoft warns that removing an allowed AAGUID blocks users who registered that key type.
- Ignoring endpoints. A stolen session on an infected laptop bypasses any login. Pair passwordless with EDR and broader cybersecurity software.
In short
Passwordless authentication for business means passkeys and FIDO2 security keys, not just magic links. CISA and NIST both treat FIDO/WebAuthn as phishing-resistant, and Microsoft Entra ID and Google Workspace already support passkeys at no extra license cost. For a 10-person team, a realistic first-year budget is about $700 to $2,300 including security keys, depending on the tool. Start with admins, write a recovery process, then enforce.

Passwordless authentication: FAQ
Is passwordless authentication more secure than passwords with MFA?
Yes, when it uses FIDO2 passkeys or security keys. CISA calls FIDO/WebAuthn the only widely available phishing-resistant authentication, while SMS codes, one-time codes and push without number matching can still be phished.
What is the difference between a passkey and FIDO2?
FIDO2 is the family of standards (CISA calls it FIDO/WebAuthn), and a passkey is the credential those standards create. Passkeys can be synced across devices or bound to one device such as a security key.
Do I need extra Microsoft licenses for passkeys?
No. Microsoft says passkeys (FIDO2) are available in all Entra ID editions, including Free. Conditional Access policies that require phishing-resistant sign-in need Entra ID P1 or Microsoft 365 Business Premium.
Are synced passkeys safe enough for a small business?
For most staff, yes. Microsoft treats synced passkeys as phishing-resistant but unattested and recommends FIDO2 security keys for admins and regulated roles.
How much does a security key cost?
The Yubico store lists the Security Key NFC at $29, the YubiKey 5 NFC at $58 and the YubiKey Bio FIDO Edition at $98. Buy two per admin so a lost key does not lock anyone out.
Are magic links passwordless authentication?
Yes, but they are not phishing-resistant. Anyone who controls the email inbox can sign in, so magic links suit low-risk apps rather than employee access to business systems.
What happens if an employee loses their phone or key?
They sign in with a backup passkey or key, or the help desk verifies their identity and issues temporary access. Write this recovery process before you enforce passwordless sign-in.
