Master Password from the developer Maarten Billemont takes an interesting approach to securing your passwords, generating each one on the fly and then erasing it after you've used it to log in, leaving no trace of the password on your device or in the cloud for hackers to intercept.


Novel approach to password security: Instead of storing your passwords in a database that you sync across all your devices, the Master Password app recreates your password every time using an algorithm that generates a cryptographic identifier based on your master password, site name, and a few other elements that is unique to your account and the site you are logging in to. Master Password is one of the three password managers the security and privacy site PrivacyTools.io recommends using.

A reasonable mix of ease of use and protection: Creating a password for each site is a multistep process where you create the password in Master Password and then paste it into an app's or website's password field. Then you can either have the app or site remember your password or have Master Password re-generate it for you to paste the next time you log in.


Or an unreasonable mix: If you're looking for a password manager that autofills your passwords and other log-in information, this is not the app for you.

Bottom Line

Endorsed by the respected privacy site PrivacyTools.io, Master Password takes a clever approach to generating passwords that keeps them from being stolen. It takes a few more steps than other password tools, but if you are serious about protecting your log-in info, Master Password is up to the task.

Developer's Description

Humans are no good at remembering lots of passwords. But writing them down or saving them is dangerous, too. Master Password avoids all the pitfalls: a cryptographic algorithm calculates your site's password for you, only when you need it. When you're done, it erases the password from the device, so it can't be stolen. Master Password's unique approach makes you safer from loss, theft, problems with backups, sync, confiscation, snooping.
