Question

How do I log into Microsoft Authenticator on new phone without old phone?

Answer 1

If you have a new phone and do not have access to the old phone that had Microsoft Authenticator installed, you can still recover your account and set up the app on your new phone using one of the following methods:

1. Use a recovery code: If you have a recovery code that you saved when you first set up Microsoft Authenticator, you can use this code to recover your account on your new phone. During the setup process, select "Enter a recovery code" and follow the prompts to enter the code.
2. Use your phone number: If you previously added a phone number to your account for account recovery, you can use this option to verify your identity and set up Microsoft Authenticator on your new phone. During the setup process, select "Use phone number" and follow the prompts to enter your phone number and receive a verification code.

Answer 2

this does not allow for if the setup was done before the number has been moved over to a new SIM for example.

eg How can I do this recovery (again) after setup?

Answer 3

Same problem. I discovered I was able to access my account through: www.myaccount.microsoft.com Then Security Info button, Update info. I added an alternate email address for verification. It sent a verification code to this email. I then deleted my old phone that it was sending Authenticator App verification to. I actually deleted all Authenticator App options on my account. I then went to login to my email through settings > Mail > add email (because I had deleted it). It went through the usual process, it wanting me to put in a code from Authenticator. This time when I chose Use Alternate Method, it only had my phone number as an option. I clicked it and it sent me a code to my new phone to put in. I now have full access to my email and administrative accounts. I will never add Authenticator to my two-step verification process again.
