Yes, RememBear is very secure — it uses end-to-end 256-bit AES encryption and a ton of high-tech security protocols to protect data, including a server key management system, secure remote password protocol, and transport layer security.
Each copy of RememBear automatically generates a New Device Key, which is never sent to RememBear’s servers. Even if a hacker was able to steal your master password online, they wouldn’t be able to log into your account without physical access to your device. RememBear’s mobile apps also have an option to enable biometric identification — so you can’t log in on a mobile device without a fingerprint or face scan.
While it doesn’t have a lot of extra features, RememBear comes with a good password generator and easy-to-use browser extensions for Chrome, Firefox, and Safari.
