Password managers

It is a tool for securely storing all the passwords that a user uses for various services (email, social networks, online stores, applications, etc.). Passwords are used to protect personal information, and they must be secure and robust and updated periodically.

It is recommended that they have at least 8 characters, and that they combine uppercase and lowercase letters, numbers, and special characters. They should also be unique and not reused.

Advantages

You only need to remember a single password to access the manager, making it easier to maintain strong and secure credentials.
In addition, the application itself guides the person to generate strong passwords.
It is more secure, since the application stores all passwords in an encrypted database.

Some examples of password managers

There is a large number of password managers. Some examples are:

Keepass
Bitwarden
PasswordSafe
Roboform
LastPass

Other ways to manage passwords

The Single Sign On (SSO) system allows you to access a service using the credentials of another service. An example would be entering an application with your Google or Facebook keys. The goal is to reduce the number of credentials, making one valid for many services, but without this implying the reuse of passwords.

SSO is an option to avoid having to remember so many passwords, but it has some drawbacks. You have to trust the SSO provider, because it attests to your identity, and if the password is leaked, the impact will be greater.
