How does the Master Password work?
All data you store in Locker is encrypted with PBKDF2 and AES-256 bit encryption that only your Master Password can decrypt. When you enter your Master Password, Locker will decrypt your data on your current device and grant you access to the vault. When you lock your vault or sign out of Locker, your data will be encrypted again.
Thanks to Zero-knowledge architecture, no one, including the Locker development team, can see your Master Password. Please note that your data will not be transferred anywhere without encryption.
