How to Create a Strong Password You Can Remember
You know you need strong passwords, but you also need to actually remember them. Here's how to create passwords that are both secure and memorable — plus a free generator for when you just want one fast.
Quick Answer
Use a passphrase (4+ random words) or let the free password generator at dotsapps.com create a strong random password. Use a password manager to store them all.
What Makes a Password Strong?
A strong password has three qualities:
- Length: At least 12 characters. Longer is better. A 16-character password is exponentially harder to crack than an 8-character one.
- Randomness: No dictionary words, names, birthdays, or patterns like "123" or "qwerty."
- Uniqueness: Never reuse the same password on two different sites.
The single most important factor is length. A 20-character password made of random words is harder to crack than an 8-character password with symbols.
The Passphrase Method: Strong and Memorable
A passphrase is 4 or more random words strung together. For example: correct horse battery staple (a famous example from XKCD).
To make your own:
- Pick 4-5 completely random words. Don't use related words or quotes.
- Combine them: "purple-hammer-cloud-bicycle"
- Optional: capitalize one word and add a number: "purple-Hammer-cloud-bicycle-7"
This creates a password that's 25+ characters long and easy to visualize. Picture a purple hammer on a cloud riding a bicycle. Weird images stick in your memory.
For truly random words, use a password generator set to "passphrase" mode.
Common Password Mistakes to Avoid
Using personal info: Your dog's name, birthday, or favorite team are all guessable. Hackers check social media for these.
Simple substitutions: "P@ssw0rd" is not clever. Hackers know about replacing 'a' with '@' and 'o' with '0'. Cracking tools test these automatically.
Reusing passwords: If one site gets hacked and your password leaks, hackers try that same password on every other site. Use a unique password everywhere.
Short passwords: Anything under 10 characters can be cracked in minutes with modern hardware. Aim for 14+ characters minimum.
Why You Need a Password Manager
You can't memorize a unique strong password for every account. Nobody can. That's what password managers are for.
A password manager stores all your passwords behind one master password. You only need to remember that one master password — make it a strong passphrase.
Popular free options include Bitwarden and KeePass. Your browser's built-in password manager (Chrome, Firefox, Safari) also works.
With a password manager, you can use the password generator to create truly random 20-character passwords for every site. You never need to remember or type them — the manager fills them in automatically.

Frequently Asked Questions
What is the strongest type of password?
A long, randomly generated password with mixed character types. A 20-character random password or a 5-word passphrase are both extremely strong.
How long should my password be?
At least 14 characters for important accounts. For your master password or email, aim for 18-20 characters or a 4-5 word passphrase.
Are passphrases better than random passwords?
Both are strong if long enough. Passphrases are easier to remember. Random passwords are harder to crack per character but impossible to memorize without a manager.
How often should I change my passwords?
Only change passwords if you suspect a breach. Frequent changes lead to weaker passwords because people pick simpler ones. Use strong, unique passwords and leave them alone.
Is it safe to use an online password generator?
Yes, if the generator runs in your browser (client-side) and doesn't send passwords to a server. The generator at dotsapps.com runs entirely in your browser — nothing is transmitted.
