Frequently Asked Questions
What does Authenticator error 2002 mean?
Error 2002 indicates a connection timeout or synchronization failure between the Microsoft Authenticator app and the authentication servers, which is most commonly caused by poor internet connectivity or an incorrect device clock.
Can I set up Outlook on my iPhone without using Microsoft Authenticator?
Yes. If your account security settings permit, you can choose 'Sign in another way' during the setup process to receive a verification code via SMS or an alternate email address instead of using the Authenticator app.
Why is the automatic date and time setting important for the Authenticator app?
The Microsoft Authenticator app uses time-based one-time passwords (TOTP). If your iPhone's internal clock is out of sync with Microsoft's servers by even a few seconds, the time-sensitive authentication requests will be automatically rejected.
