In this case, you have to weigh your own level of acceptable risk. We recommend keeping your password manager, such as Bitwarden, on as few devices as possible, and generally keeping it away from your mobile device. For passwords you need on your mobile device, we recommend using your password manager on your computer and using Signal to send the password from the Signal desktop app to the Signal mobile app on your phone. Using your password manager directly on your phone may be more convenient and there may be times where you’re not near your computer, but there is a bit more privacy and security risk in doing so.
