Symptoms:
- You receive a message indicating that changing your previous password is not possible. The message reads: "The password you entered was already used. Please choose a new password that is different from the previous password."
Cause:
This restriction is mainly a security measure.
Many platforms and service providers, including Unity, implement various security policies to protect users' accounts better. One such policy is the restriction on reusing previously used passwords. This is implemented for the following reasons:
- Security Enhancement: Repeatedly using the same password increases the risk of security breaches. This policy reduces the likelihood of hackers reusing previously compromised passwords.
- Preventing User Errors: If a previous password is weak or predictable, reusing it can expose the account to security threats. To prevent this, users are not allowed to reuse passwords from previous settings for a certain period or at all.
-
Compliance with Policies: Many companies and services adhere to standard security guidelines designed to enhance user password safety following international best practices.
Solution:
This security policy is necessary to protect user accounts, and the restriction on reusing previous passwords cannot be changed. Instead, it is important to set a new password to maintain account security. When choosing a new password, ensure it is strong and follows best security practices.
