MICROSOFT AUTHENTICATOR

Hey there, Kelly Renee

For my account, I use a range of security methods to ensure my account is protected. I have the following:

1. Microsoft Authenticator app,
2. Windows Hello (Home),
3. Security Key.

This, along with having two-step verification enabled with a passwordless account keeps my account secure. The Microsoft Authenticator app allows you to verify a code and use a TOPT code to sign into the account from your phone. As long as you know to transfer the accounts from your previous phone to your new phone, this is a secure method.

If you don't want to use the Microsoft Authenticator app, you can use the Google Authenticator app you can download onto your phone through the Google Play Store app. For more information about Miltifactor Authentication, please check this support article: https://support.microsoft.com/en-gb/security/what-is-multifactor-authentication

Hope this helps,
Nathan

" ... to use in place of Microsoft Authenticator ... "

I'm not sure what that means. Are you considering a different authenticator app? Microsoft Authenticator is very good for what it does, however, Google Authenticator (what I use) and Authy are also well-regarded. The choice is yours.
