passphrase2pgp VS Android-Password-Store

As far as I'm aware, Mnemonikey is the first of its kind, rhyming only with the related but conceptually different passphrase2pgp tool, from which I drew my original inspiration.

I think people should seriously consider using something like passphrase2pgp [0] in addition to a hardware key like this. That way you can have a brain key (hopefully generated with diceware or equivalent) to tie together day-to-day keys like this to a more permanent identity. I'm honestly surprised that strategy is not more widespread.

Check out Chris Wellons' tool passphrase2pgp - it does exactly what you're describing by hashing an arbitrary input passphrase with Argon2.

So the easiest way to synchronize gpg keys I found is https://github.com/skeeto/passphrase2pgp - it generates a deterministic gpg key (also ssh keys, x509 certificates...) from a passphrase. Excellent tool

One way to circumvent this is to use a strong passphrase to deterministically generate the PGP/SSH key [1] to unlock other passwords. The SSH key could grant access to a remote server with backups and the PGP key could decrypt passwords using pass [2].

I know there are tools that can generate GPG from arbitrary inputs, but what I'm really looking for is something with direct compatibility with BIP 39 or (BIP 44) phrases in particular.

What if https://github.com/skeeto/passphrase2pgp is not obviously the software to use, or doesn't exist at some later point?

My own tool, passphrase2pgp works this way. It generates both OpenPGP and SSH Ed25519 keys from a user-chosen passphrase, and it's designed to send the key straight into the ssh-agent on demand.

Derive my keypair entirely from a passphrase, with generous key stretching. I never need to worry about backing up my keys. I later extended this idea to OpenPGP and SSH, where I also exclusively use passphrase-derived keys: passphrase2pgp.

passphrase2pgp: for storing my PGP and SSH keys in my brain. Neither ever reside in permanent storage.

There is no "database", it's just a bunch of GPG encrypted files synced with git.

For Android there is https://github.com/android-password-store/Android-Password-S....

For Windows the only thing (Pass4Win) i found is unmaintained.

These are the types of applications that I really love. It stores the data in a cloud service that already has enough free capacity for say a notes app. It's like how we can store pass(1) passwords on a git repository (Sync it with Github) and use that as the destination of Android Password Store[1], and you have a easy password manager.

Password manager -Android-password-store (client for pass)

Since I store most of my passwords using https://www.passwordstore.org/, I have used mobile with https://github.com/android-password-store/Android-Password-S.... I'm happy enough with it. Sucks for getting anything into consoles, for obvious reasons.

I use Password Store.

That's the exact setup I use on my main phone. There's also https://github.com/android-password-store/Android-Password-S..., which I use on throwaway phones.

The pass command makes this significantly easier:

There's even a decent Android client:

There are Pass-compatible apps for iOS, Android, Windows, etc. I use Password Store on Android and QtPass on Windows.
