From a security perspective, it’s not a great idea to put 2 factor tokens together with your passwords. You effectively eliminate the security benefit that 2 factor provides if you do because if people get into your password manager, they have everything they need to access your accounts. The only people it helps having it all in one app are people who don’t understand the purpose of 2 factor and just see it as an inconvenience when services force it on them. I’m not sure that I’ll be changing from Aegis to BitWarden’s stand-alone authenticator, though, because Aegis is doing its job nicely.
