- 20+ characters: Overkill but why not
What Makes a Password Strong?
- Length — Most important factor. 16+ characters.
- Complexity — Mix uppercase, lowercase, numbers, symbols
- Randomness — No dictionary words, no patterns, no personal info
- Uniqueness — Different password for every account
Password Manager Recommended
You can't remember 100 unique 16-character passwords. Use a password manager: Bitwarden (free), 1Password ($3/mo), or Apple Keychain (free on Apple devices).
