LastPass provides a safe place for storing passwords, a kind of password vault that you can only access with a master password. It also helps you in your daily work with logging into websites and services. It works on your desktop PC or laptop and on your smartphone. It is free to use. It allows you to work securely with complex passwords so that this becomes very difficult. The paid variant is also useful for business purposes. You can create and manage accounts for a supplier or a social media account, for example, and share these with colleagues or external parties. They can log in (via their free LastPass account) and not see the password, but they can use it. If the account is no longer relevant to others, you can withdraw the permissions individually without having to change passwords.
