Apple and Google have both approved Blocksfinity Authenticator, so the phone app installs like any other. Your keys stay on the device, encrypted with your master password.

Both listings are published by RORO Technology LLC. Check that name on the store page before you install.

Authenticator is an on-device signing vault. Keys stay encrypted with your master password. Blocksfinity cannot reset that password.
