2FA apps such as Aegis have the ability to generate a QR Code to quickly share the secret to another device/app. This is especially useful for group settings where you have multiple users who need access to 2FA for an account.
This feature should be prioritized for Bitwarden Authenticator as it will make the sharing process much faster and generally more secure since it’s safer than having to send the full secret to someone or having to have it open and exposed while someone types it out.
