You're not the only one who has trouble remembering passwords

On average, we have over 25 accounts for websites. To be secure, your passwords need to be unique, long and complex. This makes it challenging to keep it both usable and secure.

How simple would it be if you could securely log in to any website with just your fingerprint? With Keyn logging in to websites becomes as easy as unlocking your phone.

Three reasons to use Keyn



Unlike most password managers, you don't need to remember a single password anymore. This not only makes Keyn easier to use, but also more secure.

More secure

Your passwords are only stored locally on your phone and every message between the app and browser is end-to-end encrypted, so even we cannot decrypt it.

More affordable

Keyn is simple and so is our pricing model. You can use Keyn for all your accounts for €10 / year. You can try Keyn with up to 8 accounts for free!
