How to create secure passwords — online guide
A secure password is the first line of defense against unauthorized access to your accounts. Even though most services today require two-factor authentication, a weak password still poses a serious threat. According to security reports, over 80% of breaches result from the use of weak or stolen passwords.

Secure password generatorWhat makes a password secure?
Password strength depends on several factors. The longer the password and the more varied the characters, the harder it is to crack by brute-force or dictionary attack.
Minimum 12 characters. Each additional character exponentially increases the number of combinations an attacker must check.
The password should be random — not based on words, dates, or predictable patterns.
Uppercase and lowercase letters, digits, and special characters (!@#$%) significantly increase the space of possible combinations.
Each account should have a different password. A breach at one service should not compromise your other accounts.
How long does it take to crack a password?
The table below shows the estimated time to crack passwords by brute-force, assuming 10 billion attempts per second (possible using a GPU).
| Length | Lowercase only | + uppercase + digits | + special characters |
|---|---|---|---|
| 6 | instantly | 2 seconds | 5 seconds |
| 8 | 5 minutes | 1 hour | 8 hours |
| 10 | 3 days | 3 years | centuries |
| 12 | 200 years | 34,000 years | centuries |
| 16 | trillions of years | trillions of years | trillions of years |
Most common mistakes when creating passwords
How to create passwords you won't forget?
There are several proven methods for creating passwords that are both strong and memorable.
Combine 4–5 random words into a phrase. Long, easy to remember, hard to crack.
Take a sentence you remember and use the first letter of each word.
The best method — generate fully random passwords and store them in a password manager (Bitwarden, 1Password, KeePass). You only need to remember one master password.
Password managers — are they worth it?
A password manager is an application that securely stores all your passwords encrypted with one master password. It allows you to use unique, strong passwords for every service without having to memorize them.
Open source, free plan, cross-device sync. Recommended for most users.
Paid, excellent interface, travel mode. Popular in business environments.
Open source, local — data never goes to the cloud. For advanced users.

Our generator creates fully random passwords with the option to choose the length and character set — directly in the browser, without sending data to a server.
Open password generatorTwo-factor authentication (2FA)
Even the strongest password can be stolen through phishing or a database breach. That is why you should always enable two-factor authentication (2FA) wherever possible. Apps such as Google Authenticator, Authy, or hardware keys like YubiKey add an extra layer of protection — even if someone knows your password, they cannot log into your account without the second factor.
Frequently Asked Questions (FAQ)
Minimum 12 characters — the longer the better. Passwords of 16 characters or more are practically impossible to crack by brute-force even with specialized hardware. If you use a password manager, use randomly generated passwords of 20+ characters.
Contrary to old recommendations, regularly changing your password every 30–90 days is no longer recommended by NIST (the US National Institute of Standards and Technology). Change your password when: you suspect it has been stolen, a service has notified you of a data breach, or you logged in on an untrusted computer.
Our generator runs entirely in the browser — passwords are generated locally and never reach any server. We use the browser's built-in cryptographic API (crypto.getRandomValues) which provides cryptographically secure randomness.
Absolutely not. If one service is hacked and your password leaks, attackers will automatically try it on dozens of other services (credential stuffing). Every account should have a unique password — a password manager solves the memorization problem.
A dictionary attack involves trying thousands or millions of common passwords, dictionary words, and their popular variations (e.g. replacing 'a' with '@', appending '123' at the end). That is why word-based passwords — even with simple modifications — are weak. Only fully random passwords are resistant to this type of attack.
HaveIBeenPwned (haveibeenpwned.com) is a free service that lets you check whether your email address or password has appeared in known data breaches. It is worth regularly checking your email address and immediately changing passwords for any affected services.
No — variety of character types is important, but it does not replace length and randomness. The password 'KOTKOTKOT' is weaker than 'kx9#mP2q' even though it uses only uppercase letters. The strongest passwords combine length (12+ characters), randomness, and different character types.
