TLDR for anyone who doesn't want to read the whole post:
- Passkeys are a thing you've probably seen replacing passwords for logins. They are, generally speaking, more secure and convenient to store.
- Currently, there's no standard format, so it's hard to, say, transfer between Bitwarden and 1Password, or between your browser keychain and Bitwarden.
- They're working on a standardized format to store and transfer passkeys, to avoid vendor lock-in.
- The new standard would also improve the security of transferring logins. Current mechanisms use an unencrypted csv file. This would likely involve an encrypted, direct transfer.
