How to Create a Strong Password — And Actually Remember It

What makes a password weak?

Common patterns attackers know: dictionary words, words with common substitutions (p@ssw0rd), names with birth years, keyboard walks (qwerty), and short passwords under 8 characters. Password crackers use wordlists and substitution rules — they do not guess randomly.

What makes a password strong

Length is the most important factor — every extra character exponentially increases possibilities. Randomness is second — random characters from a large set. Uniqueness is third — each account needs its own password.

The three practical strategies

Password generator: generate a random 16 to 20 character password and store in a password manager. Best for every account you do not type manually daily.

Passphrase: four random words like moon-table-carbon-river. At 25-plus characters, extremely strong and memorable. Best for computer login and password manager master password.

Modified phrase: take a meaningful sentence and abbreviate it with numbers and symbols. Best as a last resort when a password manager is not an option.

What to avoid

Do not increment passwords (Password1, Password2). Do not use personal information. Do not reuse passwords across accounts. Deliberate misspellings and pig latin offer minimal protection.

FAQ

How often should I change my password? Only when there is a reason — a known breach, suspicious activity, or shared access. Forced regular rotation leads to weak patterns.

What is two-factor authentication? A second verification (phone code or authenticator app) in addition to your password. Enable it on all accounts that support it.
