Password Security·March 23, 2026·2 min read

Over 80% of confirmed data breaches involve weak, stolen, or reused passwords. If your password is your pet’s name, your birthday, or the same combination used on multiple websites — your accounts are more exposed than you might realise.

What makes a password weak

Hacking tools test millions of combinations per second. Passwords become vulnerable when they contain common words like “password” or “hello”, personal information like your name or birthday, sequential patterns like “123456” or “qwerty”, anything shorter than 10 characters, or when the same password is reused across multiple sites.

The reuse problem: If you reuse passwords and one site gets breached, attackers immediately try your credentials on your email, bank, and social media. This technique — credential stuffing — accounts for millions of account takeovers every year.

What makes a password strong

A strong password has three essential qualities: it is long (at least 12 characters, ideally 16 or more), unpredictable (not based on any personal information), and unique — used on one account only, never recycled elsewhere.

The passphrase method

Chain together four or more completely unrelated words to create a password that is both genuinely strong and actually memorable.

Example: PurpleTrain!Coffee47Lamp
24 characters, contains uppercase, lowercase, numbers, and a symbol. Far easier to remember than “x7$Kp@2mQ9”. Pick words with no connection to you personally and add a number and symbol in the middle.

A password manager like Bitwarden generates and stores a unique strong password for every site — you only need one master password

Use a password manager

The most secure approach is to stop remembering passwords entirely. A password manager generates a completely random unique password for every site, stores everything encrypted, and fills them in automatically. You only need one master password.

Best free option: Bitwarden — free, open source, works on all devices. Takes five minutes to set up at bitwarden.com. It is the tool most security professionals recommend to non-technical people.

Passwords to change right now

Strong password security comes down to unique passwords for every account and a password manager to handle them. Start with Bitwarden today — it is free and will transform your security immediately.
