Password Lock is a tool that helps store and manage your passwords safely in a password-protected file. The tool helps protect passwords and other confidential information, such as ATM PIN codes and credit cards. Upon installation, the app would ask you to set a ‘master password’ that you will need to access all the stored passwords. The app helps categorize your information, which makes way for improved classification. Also, there is no limit to how many passwords you could store or the number of categories you can create.
