OneLogin - MFA Not Working Due to Phone Time Settings (4383148)

A user was unable to complete multi-factor authentication for OneLogin using a mobile device.

• MFA codes generated from authenticator applications were consistently rejected as invalid
• The issue was limited to a specific device
• Multiple authenticator applications were tested with the same result
• The device appeared up to date with no obvious configuration issues

The issue was caused by incorrect time synchronization on the mobile device.

The device was not configured to use Network Time Protocol through the service provider, which resulted in a time drift. This caused generated MFA codes to fall out of sync with the OneLogin service.

The issue was resolved by configuring the mobile device to use automatic network time synchronization.

Steps taken:

1. Verified device time settings
2. Enabled automatic date and time synchronization
3. Ensured the device uses the service provider Network Time Protocol source
4. Re-tested MFA after the update

After correcting the time settings, MFA authentication succeeded without further issues.
