Passwords

Metabase can allow authentication via email and password.

Metabase offers a couple controls for administrators who prefer to increase the password requirements on their user accounts.

export MB_PASSWORD_COMPLEXITY=strong
export MB_PASSWORD_LENGTH=10
    
                
Copy
    
    
                
Copied
    

The settings above can be used independently, so it’s fine to use only one or the other. By default Metabase use complexity = normal and a password length of 6. The following options are available for complexity choice:

• weak = no character constraints
• normal = at least 1 digit
• strong = minimum 8 characters w/ 2 lowercase, 2 uppercase, 1 digit, and 1 special character

By default, Metabase also prevents users from setting passwords that are in a list of common passwords (like qwerty123 and passw0rd). Changing the complexity requirement to weak disables this behavior.

On Pro and Enterprise plans, you can require people to log in with SSO by disabling password authentication from Admin settings > Authentication.
