If you have a lot of passwords, please use a password manager on your device. You only have to remember ONE password!
A password manager is a software application or hardware that helps a user store and organize passwords.
Password managers store passwords encrypted, requiring the user to create a master password: a single,
ideally very strong password which grants the user access to their entire password database.
Password managers can sync across all of your Windows, Mac, Android, and iOS devices. A few even let you authenticate on iOS or Android with your fingerprint rather than typing the master password. Most include some form of two-factor authentication, be it biometric, SMS-based, Google Authenticator, or something else entirely.
