Password Strength Checker
Type a password below to see how strong it really is — in plain English. We will also suggest a senior-friendly passphrase you can actually remember. Everything runs inside your browser. Your password never leaves this page.
Your password never leaves this page. We do not save it, store it, or send it anywhere. All checks run inside your browser.
We recommend typing a dummy password here — not your real bank password — just to see the result.
Need a strong password that you can actually remember?
Hit the button for a senior-friendly passphrase — four simple words joined with dashes and a number at the end. Long enough to be safe, short enough to remember.
Where you really need a strong password
- Your email. If someone gets into your email, they can reset every other password. Treat this one as the most important.
- Online banking and investment accounts. Use a different password for each bank.
- Government sites like SSA.gov, IRS.gov, Medicare.gov (US), Gov.uk (UK), or MyGov (Australia).
- Shopping accounts with saved cards — Amazon, eBay, grocery delivery.
- Your phone’s Apple ID or Google account. These hold your photos, contacts, and payment details.
Tip: use a password manager (like 1Password or Bitwarden) so you only have to remember one strong passphrase — see our guide to 2FA and passkeys for seniors.
Why password strength matters (and what actually works)
When hackers break into a website, they often walk away with millions of password hashes. Then they feed those hashes into a fast computer and start guessing — starting with the 100 most common passwords, then dictionary words, then dictionary words with “123” on the end. A weak password falls in seconds. A strong one takes longer than the age of the universe.
There are only three things that make a password strong. The first is length: each extra character multiplies the time to guess. A 16-character password is not twice as safe as an 8-character one — it is billions of times safer. The second is variety — mixing upper case, lower case, numbers, and symbols grows the pool of possibilities. The third is unpredictability: if your password is a dictionary word, a name, or a birth year, the attacker’s software will find it before moving on to truly random guesses.
That is why we recommend passphrases for seniors over random gibberish. “Maple-Harbor-Ginger-Robin-72” is 26 characters, mixes letters, a symbol, and numbers, and — most importantly — you can actually remember it. Random passwords like “xF!9qLm#2vZ” look safe, but people end up writing them on sticky notes, typing them wrong, and resetting them constantly. A memorable passphrase is far safer in real life.
The biggest mistake is reusing the same password on multiple sites. When one site is breached, attackers try the same password on your email, your bank, and Amazon. Every site should have its own password. That sounds impossible to remember, which is why most security experts now recommend a password manager — software that remembers every password for you. Your iPhone and Android phone already have one built in, and apps like 1Password and Bitwarden are free or very cheap. You remember one strong passphrase, and it takes care of the rest.
Finally, wherever it is offered, turn on two-factor authentication (2FA) or a passkey. Even a perfect password is no match for a scammer who tricks you on the phone. 2FA adds a second check so a stolen password alone is not enough.
Frequently asked questions
Is it safe to type my password here?
Yes. The checker runs entirely inside your web browser. We do not send your password to any server, and nothing is stored or saved. As a matter of habit, though, we recommend typing a dummy version of your password — not the exact one you use for banking — just to test the pattern.
What makes a password strong?
Three things: length (12 characters or more), variety (mix of upper case, lower case, numbers, and symbols), and unpredictability (not a dictionary word, not a birthday, not one of the top 100 most-used passwords). The single biggest factor is length — a 16-character passphrase beats a short clever one every time.
Why do you suggest four-word passphrases instead of random gibberish?
A passphrase like "Maple-Harbor-Ginger-Robin-72" is both strong and something a human can actually remember. Random gibberish looks safe but people write it on sticky notes, which defeats the purpose. Length plus memorability wins.
How often should I change my passwords?
Modern security guidance (from NIST and others) says you do not need to change strong, unique passwords on a schedule. Change a password only when there is a reason: the site was breached, you shared it with someone, or it was weak to begin with. The most important habit is using a different password for every site.
Do I need a password manager?
Strongly recommended. A password manager (like 1Password, Bitwarden, or the one built into your iPhone or Android) remembers every password for you, so you only need to remember one strong passphrase. It also warns you if a site you use has been breached.
