Your Master password is the secret key that unlocks your encrypted Vaulted account, without which your account can never be decrypted. Only you know your Master password, and it is never stored by Vaulted.
If you have forgotten your Master password there are a few options to recover your account. Below is an interactive guide that will walk you through the recovery process.
At the end of this guided recovery process, if you are still unable to recover your Vaulted account and have forgotten your Master password, unfortunately this means your data stored in Vaulted can no longer be decrypted and your account must be reset to begin using Vaulted again.
