What is Master Password?
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.
A master password should be strong enough to protect your vault. It should include at least 12 letters and contains special symbols.
Worrying about forgetting your master password? Try the following tips.
- Set up a password hint. Once requested, Locker will send you an email with the Master Password hint to help you retrieve your memory.
- Add a trusted emergency contact. Premium users can grant access to a trusted account in case of emergency. See more at Premium plan.

As long as you remember your current master password, you can change it whenever you want.
- In your web vault, click Settings on the sidebar.

I Forgot my Master Password
As previously stated, Locker works on the basis of zero-knowledge architecture to ensure you are the ONLY person to know your master password. Therefore, Locker has no way to retrieve your master password if you forget it.
The only option is to reset your Locker account and start creating your vault from scratch again. However, you can try some following tips before resorting to the last straw.
- Try logging in using another device.
- Get a master password hint. If you set up a master password hint, Locker will send it to your inbox once requested.

- If you are a Premium user who have set up emergency access, you can regain access to your vault via your trusted emergency contact.
If none of this works, you may have to delete your account and register a new one. Before deleting your account, check if you are still logged in on any device to export all your data and import to the new vault.
