    I used Google authenticator for years and I’m glad I switched. There are excellent quality of life features, such as focusing the search bar upon open, copying the next OTP, and I find it easy to add new entries (even when manual). There is one thing I wish Proton Authenticator had, and that’s the ability to export all entries as a series of QR codes. GAuth has that, and I do miss that feature (because it made moving or copying codes to another device extremely easy, without saving any information to any filesystem). Add that, pretty plz. Keep up the good work Proton people, and remember: your products are good because they tend to do one (or a handful) of things very well. Stay true to that, and you’ll receive my yearly payment until I depart.

  • Apple restore from backup does NOT restore Proton Authenticator keys

    Do manual backups from app. These Apple undocumented features will always keep you on your toes. Proton - support iOS native backups.

  • Yen has ruined brand and product

    Andy Yen has single handedly destroyed his product and tainted the entire operation from within. His hatred of labor and by extension proton is an embarrassment. Nothing about proton is irreplaceable. A thoughtful customer would run for the door. I’m kindly headed for the exit. Do the same.

  • You won’t find better anywhere

    Proton Authenticator is the absolute cream de la crème of 2FA. Not an opinion, but a fact
