Setting up complex passwords filled with cryptic characters is one of the best ways to keep hackers off your tail. After all, a 15+ string containing weirdly-arranged alphanumeric strings and symbols is a lot more effective at thwarting brute force and dictionary attacks than awful, easy-to-guess passkeys. The downside is that you’ll have a hard time recalling your wacky passwords, especially if you have different login credentials for all your accounts.
