Not as good as Ente yet but they've worked out all the major issues since first launch and now I use this as backup. It's easily the 2nd best behind Ente and the only other TOTP authenticator I recommend.

I'm truly honored to be using this app right from version 1.0.0, mere hours after it was announced on the site. The sync feature with my Proton account is a game-changer. UI/UX-wise, it's as smooth as Proton's other offerings. That said, the icon selection is limited and non-customizable at the moment. Still, it meets my needs perfectly for a v1 release, working great on both desktop and mobile. I've tried tons of auth apps in the past—Google Authenticator, Microsoft Authenticator, Ente Auth, 2FAS, Aegis, you name it—but I'm switching to Proton full-time, with Ente as my backup plan.

Recommended Software for the Average Joe and Jane [1/3]

Part 1 of 3 in Series: lists will continually be updated periodically. Criteria I look for universally for my lists are as follows: — Open source code: publicly audited — Privacy-focus: minimal data collection, encryption by default — Security-focus: 2FA available, encryption by default — Zero Knowledge end-to-end encryption (E2EE) when appropriate — Cross-platform or progressive web apps (PWAs) + cloud backup/sync — Freemium subscription model, so basic features are always available for free — Oligarchy / Big Tech alternative — Absence of "dark" or deceptive patterns Criteria specifically for this list: — Established companies with a strong reputation — Provides a "it just works" experience for the user: minimal configuration, user friendly — Features available can easily replace Big Tech’s popular apps
