I use KeePassXC and a Yubikey 5. You can store a certain number of 2fa on the key but i also back up the secret key and recovery codes on KeePassXC which is backed up on my Nextcloud. When using the Yubikey there is an app on desktop and mobile that reads they key but doesn't store the codes. Open the app, plug in the key, the TOTP appears, take the key out and the TOTP is gone.
I like using bitwarden, the selfhosted vaultwarden server stores it with passwords and makes codes available in the app / browser extension. I also keep them backed up on a nas and synced off-site just in case.
1Password has impressed me. I’ve used KeePassXC, LastPass, Bitwarden (but not extensively and one of the early versions), and even CyberArk (🤮).
1Password is closed source but it’s one of those pieces of software that just works the way you expect it to. Hard to confirm a lot of their security claims. Just rolling with “Have not heard a lot about 1Password breaches” mentality.
We got lucky at work and used it to replace an unmanageable long list of KeePass database files that were sprawling everywhere. With that everyone who uses 1Password at work gets an associate private family account. Made managing my kids passwords and share some of our common family passwords way easier and I still get to lock them out of my passwords I don’t want them using.
I believe modern Bitwarden for enterprise has a similar licensing sweetener with a private family account for each corporate account.
AndOTP is great. Its free and had simple and easy encrypted backups. I love how its timer counts down, not up like some others and highlights the token in red so you know you need to hustle or wait.
A lot of password managers support 2fa now. I use Enpass because I got a lifetime license a long time ago (it's also available to people with Google Play pass), but I know some other popular options have it too.
The whole point of 2FA is to keep the second factor separate from the first. If you store both in the same password manager app that defeats the entire point of 2FA.
It still protects you from your passwords being compromised in any way except through a compromise of the password manager itself. Yes, it's worse than keeping them separate, but it's also still much better than not having 2fa at all.
I only switched to keepass due to the fact that nothing seems to support a desktop application like authy did. Not everyone keeps a phone on them 24/7. If they don't want that risk they would allow desktop apps. least in my opinion
