Which of the following practices is NOT recommended for password security?

Reusing the same password across multiple accounts significantly compromises password security. When a password is reused, if one account becomes compromised due to a data breach, all other accounts using that same password are jeopardized as well. This creates a cascading effect that can lead to unauthorized access across multiple platforms. Each account should be protected with a unique password to mitigate the risk associated with password exposure.

In contrast, using a mix of letters, numbers, and symbols enhances the strength of a password, making it more difficult for attackers to guess. Changing passwords periodically keeps the security of accounts fresh, limiting the time frame in which a compromised password can be exploited. Enabling two-factor authentication adds an additional layer of security, further protecting accounts by requiring a second form of verification beyond just the password.
