Looking for something to secure your passwords, automatically fill in credentials, or simply give peace of mind when surfing the Internet? Well, Locker is the solution to all your needs, and what’s left to do is to get your Locker account ready.

Deleting your Locker account means deleting all your data in Vault, and you can no more log in to your account.

If you have already signed up for a Locker account, you may notice that Locker requires both a Password and a Master Password for your account.

Your Master Password is the primary key to your vault. It is the ONLY password you have to remember, and you are the ONLY one to know your master password.

Locker works on the basis of zero-knowledge architecture to ensure you are the ONLY person to know your master password.
