Describe the solution you'd like

• Display the key identity in the prompt
• When multiple keys are available, allow the user to select which key to use for decryption

This aspect of the app can definitely use some improvement. Currently the app will go through each identifier it parses from your .gpg-id file and attempt to decrypt using the provided passphrase and the corresponding key for that identifier so it'll probably work but the user experience is nonsensical.

If you can set up an example pass repository for the multiple keys use case similar to pass-test it'll make my job somewhat easier, otherwise I can do it when I find time to work on this.
