Authority.Ecto.Changeset.validate_secure_password/2 would validate that a password meets minimum security requirements. Presumably, these would include length and symbol checks.

# Check that the password meets agreed-upon password strength checks
validate_secure_password(changeset, :password)

The checks could be configurable, or we could just assume the "best" ones and let you fall back on the built in Ecto functions if you don't like it.
