A password validator typically checks several criteria to assess the strength of a password. Here are some common features and checks performed by a password validator:
Length Requirement: It verifies if the password meets a minimum length requirement. For example, it may require a password to be at least eight characters long.
Character Complexity: It examines whether the password includes a combination of different character types, such as uppercase letters, lowercase letters, numbers, and special characters. This check promotes the use of complex passwords that are harder to guess.
Error Messages: It provides meaningful and specific error messages to guide users in creating valid passwords. This helps users understand why their password is being rejected and provides suggestions on how to improve it.
