Hello Tanner,I know these are basic steps. Have you attempted to perform the below steps ?
- Reinstall the Microsoft Authenticator App on your device.
- Ensure your devices date and time settings are accurate and set to automatic.
- Visit https://mysignins.microsoft.com and login with your email id.
- Under "Security Info", manage your sign-in verification methods.
- Delete the Microsoft Authenticator option and then re-add it.
- When re-adding the Authenticator, you should receive a new QR code to scan on your computer screen.
Let me know if this works. Thank you.
Regards,
Mrinal.
