Selfhosted

I use Aegis, it works well

I like Aegis.

Bitwarden. I don't self host it, though. $10 a year for password management and 2FA is fine by me.

I've been using KeePassXC. I use Syncthing to keep the database synchronized between computers.

I use Aegis on my phone.

Aegis ♥️

Aegis

Aegis.

I like the auto backup feature (encrypted) . Then the backup is synced to computer via Syncthing.

Set and forget setup.

Bitwarden

I've been using Aegis for several years now without any problems. It replaced the Google Authenticator seamlessly.

Aegis

Bitwarden Authenticator because Bitwarden seems to have a good reputation. I don't use their password manager, though.
It does seem faintly insecure that it displays all of the codes at once on one page, but I'm having trouble imagining a scenario where it's actually a problem.

Enteauth

Proton Authenticator. Has both Desktop and Mobile apps. Free. Don't have to sync to Proton.

2FAS Authentication

Yubikey. I dont want to trust my phone, so I use some separate hardware instead

1password

Aegis seems like a pretty good 2FA app on Android from what I’ve heard. Personally, I use Ente Auth as sync is very helpful when I don’t have my phone nearby (you can either use the desktop app or use your browser, both work). Don’t think you can self-host sync, though I might be wrong. Ente Auth also works without sync, so there’s that.

I would not suggest using a password manager’s 2FA integration (e.g. Bitwarden, I think Proton Pass has one if you use that?) as it kind of defeats the point of 2FA, since if someone got access to your password manager, they would also get the 2FA codes.

Ente

Vaultwardwn/bitwarden + a yubikey for bitwarden itself and a few others

keepassxc and a yubikey. And syncthing to keep all devices in sync

I use Aegis, automatically backed up every time a new key is added. Was using Authy for a while, but they're going down the enshittification hole, so I dumped them.

Yubikeys. I have 2 of them and both have the same entries in case one breaks.

Authenticator and Authenticator.

Damn thoe innovative tech companies, what will they think of next.

I use Proton Authenticator on an iPhone without an account and I am satisfied

Yubikey for 2Fa codes also works well for sudo and su (2Fa) or if you still use Windows I think it supports single sign on there. Absolutely worth the purchase have had my keys for years.

Bitwarden as Vaultwarden enables TOTP.

FreeOTP/FreeOTP+

depending on your goal for this (real 2fa vs just simulated) you shouldn't have sync in the first place.

you could also look into security keys (hardware solution, webauthn/FIDO2) as an alternative that has strong security with good user experience (no typing anymore), but they're not as widely accepted.

Adding to the Aegis chorus.

I also use Proton Pass for some sites that aren't as critical for me / don't have a bunch of PII. It's easy.

I use bitwaarden and stratum since it has a wearos app as well and it's nice to use that for 2fa codes

What you mean syncing with Gnome app?

Yubikey. It supports TOTP as well as passkeys. Plus is a physical device separate from my phone. Recommend getting 2 to have 1 as backup

I personally use Ente Auth and quite like it, don't use syncing and save an encrypted copy to my PC. I really like that you can see what the next code will be.
