It's just a bunch of gpg encrypted files with as much stuff as you want in them, in any format you want (password on first line). Easy to share/sync to whatever you want. Lots of interfaces on lots of platforms but you really don't need an interface.
Has git support...
Essentially, I accidentally publicly exposed my private key. I thought I was clever for writing a Python script to dump all my passwords and then re-add them after setting up pass with a new key.
A year later, when I accidentally deleted my private key (reformatted laptop, phone bricked before set laptop back up), I spent a few hours trying to figure out if I made a mistake that would let me recover my passwords. I was very motivated :)
Eventually, I realized that since I'd been using git to sync pass between my phone and computer (the recommended setup) I could access versions of my encrypted data for every account more than a year old and decrypt them with the private key I leaked. I got back almost all my data.
Luckily I was using a private git repository for defense in depth, but many guides recommend a public reposity because they say gpg is very strong.
It all works, but only if you don't do something dumb like I did. Now I'm on 1password and happy knowing that experienced people are paid to make it and smart security researchers like Troy Hunt (of haveibeenpwned fame) have said it's the most secure password manager they've looked into.
(I said the same thing earlier in a different post)
Emacs is good at automatically keeping gpg files. Not sure about mobile support.
Password managers with password generators and 2FA code generators are ok for work related use, but they usually may not cover other pieces of information, like credit/debit cards, software licenses, identification cards, hardware/appliances, etc. Adding custom fields in each entry by oneself isn’t a great option. Perhaps it’s not a great idea (even with a very strong master password) to put all the information in one database, but I see value in being able to store, retrieve and auto fill different kinds of information (even if some may seem too complex to define in a generic schema).
I already tried Bitwarden, but it covers only passwords, cards and identities (plus secure notes).
