Microsoft Authenticator is a two-factor authentication app for customers to log into their accounts. It can allow passwordless login; react to a user name / password signup prompt for authentication; or behave like a code generator for all other authenticator app supporting accounts. Microsoft has gradually developed this function over the previous few weeks. As of today, September 12, “there’s 100% now for version 6.6.0 + accessible,” states the Microsoft blog article. Credentials are updated even if customers add, delete or edit accounts, authorities have said. To enable cloud backup, Authenticator users can go to settings and then set the cloud backup toggle on under “Backup.” To retrieve account credentials on a fresh machine, customers can pick “Begin Recovery” as an account option to log in with their earlier Microsoft account. For iOS and Android phones, Microsoft Authenticator is accessible. On iOS, users need an iCloud storage location account. Android and iOS users both need a Microsoft personal account to be able to retrieve their accounts. Authenticator only stores private and third-party credentials for customers, i.e. user name and account verification code to demonstrate identity. There is no other account data stored, representatives of Microsoft claim. Credit:ZDNet
