pass can encrypt to multiple keys. I use one key for my laptop and one for my phone. If someone gets your gpg key then they can decrypt all your passwords if they also get the repository. It would be prudent to change all your passwords in this case (pass-rotate could help a little with this). If you lose the key, you lose access to all your passwords.

worth also noting that that when I used to use Android, I didn't need multiple keys - my GPG key was on my yubikey neo, and i could plug it into my laptop to decrypt passwords there or tap it to my phone to decrypt passwords there. not possible on iOS due to Apple not opening up NFC to developers, so now I have pass set up to encrypt to two keys.
