Best practices that matter more than length

A strong password helps. But real breaches are almost never brute force — they're phishing, reuse and data leaks.

Use unique passwords

Never reuse passwords across different sites or services.

Minimum 12 characters

Longer passwords are exponentially more secure.

Use a manager

Store your passwords in a secure manager like Bitwarden or 1Password.

Activate 2FA

Two-factor authentication adds an extra layer of security.

Beware of phishing

The #1 cause of hacked accounts isn't a weak password — it's the owner typing it into a fake site. Always verify the domain before typing.

Check if your email is leaked

Search haveibeenpwned.com with your email. If it appears, rotate passwords on every service that shared that key.

What actually makes a password strong?

Three principles that move the needle, in order of real impact.

01

Length beats complexity

Each extra character doubles the crack time. A 20-character lowercase password is stronger than an 8-character one with symbols.

02

Unique per site

80% of breaches use reused passwords. If one small site leaks your key, attackers try it on your banking, email and socials.

03

Random, not human

Human-invented passwords follow predictable patterns (words + year + !). A CSPRNG-based generator has no bias.

Passwords are only one layer

Your IP, your DNS and your email metadata also reveal who and where you are. Protect the whole connection.
