The option that shows that the site or app may not have strong enough rules for creating passwords is:
A, B, C, D and E
All of these options indicate potential weaknesses in password policies and security practices:
- A: A very low character requirement or no minimum defined at all weakens password strength.
- B: Not allowing special characters limits password complexity, making it easier for attackers to guess.
- C: Sending credentials via email can expose them to interception and isn't secure.
- D: Emailing a new password can risk sending sensitive information over insecure channels.
- E: Not confirming the old password when changing it could enable unauthorized changes to account settings.
Therefore, all of these factors indicate potentially weak password policies and security practices.
