Heard the first time about them (ente) yesterday in a discussion about "which 2FA are u using?". Directly switched to https://ente.com/auth/ on Android and Linux Desktop and very happy with it.
Going to give this a try...
Oh, wow, thanks for posting that. I switched to Ente for my photos recently, had no idea they also have a 2FA app. I was looking for a replacement for Aegis (after a switch to iOS), and this can even import from Aegis backup files. Neat. This means I can finally ditch my old phone I still had to have around just for 2FA :)
You presumably had a working 2fa app already, but off the cuff decide to switch to new unvetted variant X; basically unknown auth system after reading a few paragraphs of text in an afternoon?
Does this seem sound?
