A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
If no mobile phone is available, sign in with another verification method if one was set up earlier.
- On the sign-in page, select Sign in another way.
- Choose an alternative method such as office phone, text message, or phone call if it appears.
- Complete the prompts to finish verification.
If Sign in another way does not appear, or no other method is available, the account does not have an alternate verification method configured. In that case, contact the organization’s IT help desk or administrator to clear or reset the MFA settings so registration can be done again.
If the missing phone was lost or stolen, Microsoft also recommends notifying the organization’s Help desk so they can clear the settings. After the settings are cleared, registration for two-factor verification is required again at the next sign-in.
