Generating Safari-style passwords using the PrivateFramework WBSPasswordGeneration class on macOS via python & pyobjc

ck_passwords.py

# For an alternative method, check out:

# Note: this method no longer works for Safari 15+

    password = WBSPasswordGeneration.generatedPasswordMatchingRequirements_(rec)
    # Do a little cleanup, since we don't actually want to save any CloudKit records
    del rec
    return password

# Example usage
# >>> generate_password()
# u'hhs-o7X-kaZ-ngw'
# Returns an iCloud Keychain suggested password in the style seen here:

# Alternatively, you can define various keys in a dictionary and pass it in
# >>> r = {
# >>>      'PasswordMinLength': 20,
# >>>      'PasswordMaxLength': 20, # These keys only seem to force length if you set them both to the same value
# >>>      'PasswordRequiredCharacters': ['abc','123','!@#$', 'XYZ'],
# >>>      'PasswordAllowedCharacters': "abc123!@#$XYZ", # allowed characters has to be set if you're requiring sets
# >>>      'PasswordFirstCharacterCandidates': '1a',
# >>>     }
