Any obvious holes in keeping a text file on my laptop that I encrypt when not using it? Using ccrypt on linux.
I do not want my passwords - even encrypted - on the cloud or at the mercy of a 3rd party in any fashion.
Use KeePass.
My concern with using a text file is you have to defrost it to use it and whenever it's not encrypted it's potentially exposed. You are also vulnerable to keyloggers or clipboard captures
KeePass works entirely locally, no cloud. And it's far more secure/functional than a text file.
I personally use KeePass, secured with a master password + YubiKey.
Then I sync the database between devices using SyncThing over a Tailscale network.
KeePass keeps the data secure at rest and transferring is always done P2P over SSL and always inside a WireGuard network so even on public networks it's protected.
You could just as easily leave out the Tailscale/SyncThing and just manually transfer your database using hardware air-gapped solutions instead but I am confident in the security of this solution for myself. Even if the database was intercepted during transit it's useless without the combined password/hardware key.
Is there a recovery process if your yubikey breaks?
There is no recovery if you have a single hardware token in use only. But that's a structional issue with your concept.
Instead, it is recommended to have two (or more) identical Hardware Tokens to replace one that dies.
It is also smart to keep the seeds for things like 2fa in some secure backup with schizophrenic paranoia proof Security measures.
