Credentials are what you use when you sign-in or login to a service or app.
Credentials can be a combination of username, passphrase, or tokens. In some systems, usernames are email addresses.
Password managers are used to improve the security of credentials.
Credential stuffing is a common attack exploiting a common practice of reusing the same username-password combination across multiple services.
