How to create strong passwords and test their strength
Most account takeovers come from weak, reused or predictable passwords. A strong password is long, random and unique per site. This guide shows how to generate one and how to verify its strength before you use it.
What actually makes a password strong?
Length beats complexity. A 16-character random password has trillions of times more combinations than an 8-character one, even if the short one has symbols. The best approach is a generator that picks from a large alphabet: upper and lower case, digits and symbols, with no word patterns an attacker could guess.

- Use a unique password for every account.
- Store them in a password manager, not a note file.
- Enable two-factor authentication where possible.
What about passphrases?
A passphrase — several random words joined together — is easier to type and memorize while staying strong. The Random String Generator can build memorable combinations too, giving you the same protection with less friction.
