Best Authenticator App

This has been the best Authenticator app that I’ve personally used (and I’ve used several). Works very well for everything you can ask for with this kind of app and I love the peace of mind it brings with knowing they’re not harvesting unnecessary personal data. I’m not a fan of the fact that the encryption keys for windows OS desktop app is stored locally…defeats the purpose in my eyes for privacy and security, hoping that’s updated in the future. I also am hopeful for it to fully integrate/sync with proton pass eventually if you choose to opt into that. I’d recommend the use of this app to anyone.

Sehr gut Backup über iCloud

Not Bad

Let down by a few things:

a) No browser extension.

b) Can’t manually choose an icon for a brand like you can in other software (i.e. cant choose Microsoft icon for Microsoft login).

I note that some issuers are auto assigned an image
