Total Defense Security Tip of the Day

The password refresh: set expiration dates and stop hackers cold
You know the drill: pick a strong password with letters, numbers, and symbols. Good job! But here's the uncomfortable truth: even the strongest password has a shelf life. Hackers are always working to crack combinations, and data breaches are constantly exposing login credentials.
If you use the same password for years, you’re giving a determined attacker an extended window of opportunity to figure it out, either through brute force attacks or by finding that password exposed in an old, forgotten data leak.
It’s good practice to change your passwords frequently enough to stay ahead of the curve. And the easiest, most active way to enforce this crucial habit is to set expiration dates for your passwords on your private accounts.
Why Password Expiration is Your Best Defense
Think of password expiration as a security check-up enforced by the system. Most professional or sensitive accounts—like banking, corporate email, or investment platforms—already require you to change your password every 60 or 90 days. You should apply that same philosophy to your personal, highly valuable accounts, too.
Here’s why setting an expiration date works:
1. It Limits the Hacker's Window
If an attacker manages to steal your password in a data breach, and you change that password every three months, the time they have to use that stolen credential is dramatically limited. A password that was compromised in January is useless by April. You cut off their access before they can do significant damage.
2. It Forces a Fresh Start
When you set an expiration date, the system often requires you to change your password and, crucially, typically prevents you from repeating old passwords. This is a huge security win! If you simply reuse the same old password you used three years ago, you haven't actually made yourself safer. The required change forces you to create a genuinely new, strong password.
3. It Enforces Stronger Habits
A rotating password policy reminds you of the essential elements of a good password: coming up with strong combinations of letters (uppercase and lowercase), numbers, and symbols. If you are forced to create a completely new, unique password every few months, you are more likely to rely on a secure method—like a password manager—rather than falling back on simple, guessable words.
How to Set Up Your Password Refresh Cycle
While not all websites allow you to set your own expiration date (they either enforce one or they don't), you can actively manage this process using a dedicated tool:
- Use a Password Manager: This is the easiest and best way. A quality password manager not only creates unique, strong passwords for you but also often includes a feature to flag passwords that haven't been changed in a set amount of time (e.g., 90 days). This gives you a clear reminder when it's time to cycle out your login.
Don't wait for a data breach to force your hand. Take an active role in protecting your accounts by implementing a password rotation policy today.
