The 5 most common password mistakes and how to fix each one today

How this is calculated

Password reuse is the number one cause of account takeover. One breached site exposes the password, and attackers try it on every other service. A password manager fixes this instantly by generating unique passwords. Short passwords are crackable by GPU clusters in hours to days. The fix is simple: use 16+ characters. Sharing passwords via text or email leaves a permanent unencrypted copy on the recipient's device, your device, and the service provider's servers. Use a password manager's secure sharing feature or an encrypted messaging app with disappearing messages. Storing passwords in unencrypted notes means anyone with access to your unlocked phone or computer can see them. Password managers encrypt at rest. Skipping 2FA leaves you with single-factor authentication. Enable it on email, banking, and any account with payment methods.

Verdict

Two tools close every one of the five failure modes. Reuse dies because the manager generates a fresh string per account. Short passwords stop because 16 characters is the default. Unencrypted sharing gets replaced by the manager's secure-share feature. Storing in Notes or a sticky note gives way to an encrypted vault. And missing 2FA is a one-time toggle. The whole setup runs in about 10 minutes and pays off the first time a non-critical site breaches.
