Rolling Out Passkeys in Microsoft 365 Without Locking Anyone Out
Start with the Microsoft Authenticator app, which already supports passkeys on the phones your staff carry, and turn on the passkey authentication method in Entra ID for a pilot group of five to ten people, including at least one person who is not technical. Register two methods per person, a passkey plus a backup such as a hardware key or Temporary Access Pass held by IT, so a lost phone is an inconvenience rather than a lockout. Once the pilot has run for two weeks, expand by department, and only then use Conditional Access to require phishing-resistant authentication for admins, finance and anyone with access to client data. Leave a documented break-glass account with a long password stored offline.
Business Benefit
Passkeys cannot be phished, replayed or fatigued out of a tired employee at 4:55 on a Friday. Sign-in is faster than typing a password and a code, help desk password resets drop, and “phishing-resistant MFA” becomes a box you can tick honestly on the next cyber insurance renewal.
