Review summary

Users praise 2FAS for strong security/privacy, simple usage, and useful backup options (cloud backup, Drive syncing, importing codes). However, multiple reviews note reliability problems: codes/backups sometimes disappear or fail, causing lockouts or access issues, with some reports of authentication failures. Overall, the app is seen as secure and easy to use, but reliability concerns temper enthusiasm and suggest planning for potential data/access problems.

Pros

Strong security and privacy (offline OTP generation and no data collection)
Easy to use with a clean, ad-free UI
Cloud backup and cross-device syncing (Google Drive) and ability to import codes from other apps
Ad-free and free to use
Highly regarded as among the best 2FA apps

Cons

Reliability issues with codes/backups causing access problems (codes disappearing, backups failing, potential lockouts)
Occasional authentication failures leading to inability to access accounts (failed to authenticate)
