I'm programming a timeclock system where a user effectively punches their timeclock by entering their username and password in a specific computer. A timeclock user will first login. I just need to register that a user showed up by checking if the username and password they entered is correct. How can I do that in Devise?
I don't want to actually log them in, only check that they are who they say they are. The timeclock user is the only user logged in at all times.

Note: If the password or user account is not correct, it will produce an error with the code 1326: the username or password is incorrect. This process is basically the same as described in method one, but this time, via the GUI.
Check a user's password against the organization's password validation policy and report whether the password is valid. Use this action to provide real-time feedback on password strength while the user types their password. One of the following permissions is required to call this API.
Password checker program basically checks if the password is valid or not based on password policies mention below: Password should not contain any space. Password should contain at least one digit (0-9). Password length should be between 8 to 15 characters. Password should contain at least one lowercase letter (a-z).
Testing a credential for the existence of an account would be a matter of using net user or dsquery. The net user command won't tell you if an account is locked out, but querying the lockoutTime attribute of the user account could tell you that.
If you use gem devise. Try
User.find(1).valid_password?('password123') # returns true/false
That code in file: devise/lib/devise/models/database_authenticatable.rb

Devise gives you two built-in methods that let you do exactly this:
user = User.find_for_authentication(username: params[:username])
user.valid_password?(params[:password])
