With so many accounts an average internet user has today, it has become impossible to memorise all passwords and have them be unique, long, and complex at the same time.

That is why you should use applications called password managers, which securely store your login credentials and protect them with a master password. That way, you only need to remember your master password and you can copy/paste your other credentials directly from the app. Password management software usually has the option to automatically generate a long and complex password, made of randomised characters and symbols.

Applications commonly used for password management are KeePass, KeePassXC, and Bitwarden. KeePass provides a tutorial for the first steps after you install the application and KeePassXC also offers a detailed instruction page for new users. When it comes to Bitwarden, before you start using it you need to register for an account and log in to the app type of your choice, e.g. browser add-on, desktop app, or mobile app.

Storing login credentials in browsers should be avoided, together with online password managers which are not open source and end-to-end encrypted.
