Ente Auth review

Ente Auth is the authenticator we would suggest to most people starting with two factor authentication, because it solves the lost-phone problem without charging for it. Codes are backed up to Ente's cloud with end-to-end encryption, and Ente says its cryptography has been externally audited. Every new device you sign into gets your codes, and there are apps for iPhone, Android, Mac, Windows and Linux plus a web app at auth.ente.io, so you can read a code from a work laptop. The app also runs offline and can be used without an account if you prefer local storage only. Day-to-day touches include a preview of the next code, service icons, notes, tags, pinning and search. You can add codes by QR code, by pasting a secret or by bulk import, and export them back out in the otpauth text format. The trade-offs are small: exports are unencrypted text, and the iOS listing is English only.
