Passwords

Metabase can allow authentication via email and password.

Password complexity

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

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.

Metabase Cloud passwords

If your instance is hosted on Metabase Cloud, passwords must:

• Be at least 12 characters long
• Contain at least:
  • 2 lowercase letters
  • 2 uppercase letters
  • 1 digit
  • 1 special character (!,$,%, etc.)

Disabling password logins

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