If you have a lot of passwords to store, the best way to do this is to use password managers. They are applications that you can install on your cell phone and computer, which register the links, logins and passwords for your web accounts and general services, protecting everything with a master password (the only one you will need to remember) and biometrics. See the best options:
How do managers work?

Generally speaking, a password manager stores all passwords, logins, access links and other data that you have registered for your accounts, so that you can access them in the future. Some of them even detect that you are accessing the website or web service, and remind you which password you used or suggest saving this data when you access it for the first time.
And, best of all, using a password manager, you only need to remember one master password, which is used to grant access to the manager. It can also be supplemented by PIN, a 4 or 6 digit code, and biometrics, such as your fingerprint or Face ID.
Password managers are also multi-platform, that is, designed to be used on cell phones and tablets, as well as on notebooks and desktops. This means you will have easy access to them anywhere, with data updating and backup.
