The Bitwarden Authenticator app is introducing a feature where user data will be backed up through the mobile operating system's backup services. This means data from the app will be saved alongside other system backups, which is a significant departure from many apps that rely on proprietary cloud services. Some users express confusion over whether this new app is necessary since Bitwarden has already had similar functionality integrated into its main offerings. The lack of a PC app and device syncing capabilities has also raised questions among users, with many seeking alternatives such as Aegis and FreeOTP+. Overall, there's a mix of acceptance for the new approach, reflecting a desire for autonomy over data storage without dependency on external cloud services.
