Frequently Asked Questions
Why did Microsoft switch my sign-in method from SMS to Authenticator?
Microsoft actively encourages the use of the Authenticator app over SMS for multifactor authentication (MFA) because app-based approvals are generally more secure and less vulnerable to SIM-swapping or phishing attacks.
Can I remove the Microsoft Authenticator requirement without logging in?
No, you must first verify your identity through the account recovery form or use an alternative backup method previously set up on your account to access and modify your security settings.
What should I do if my Microsoft account recovery form is rejected?
You can submit the recovery form up to two times a day. Try to gather more detailed information, such as old passwords or subjects of recently sent emails, and submit the form again from a recognized device or familiar location.
