Strong Password Generator
Generate unbreakable passwords instantly. Fully client-side — nothing is ever sent to a server or stored anywhere.
What makes a password truly strong
Not all passwords are equal. Understanding what makes a password strong helps you make better choices beyond just using a generator.
Length Is the Biggest Factor
Every additional character multiplies the number of possible combinations exponentially. A 12-character password with all character types is vastly stronger than an 8-character one. Aim for at least 16 characters for critical accounts.
Entropy = Unpredictability
Entropy measures how unpredictable a password is, in bits. Each bit doubles the possible combinations. A 70-bit password has over a trillion trillion combinations. This tool shows your entropy score in real time.
Character Variety Matters
Using uppercase, lowercase, numbers, and symbols together increases the pool of possible characters per position. More variety per character = exponentially more combinations for attackers to brute-force.
Avoid Predictable Patterns
Passwords like "Password1!" or "Summer2024" look complex but follow patterns that dictionary attacks target first. Truly random passwords generated by this tool contain no exploitable patterns.
Never Reuse Passwords
Even a strong password becomes a liability the moment it is reused across multiple accounts. When one site is breached, attackers try the same password everywhere. Each account needs a unique password.
Use a Password Manager
The only practical way to have a unique, strong password for every account is to use a password manager. Tools like Bitwarden (free) or 1Password store and autofill your passwords so you only remember one master password.
Which is right for you?
Passwords and passphrases are both strong when generated correctly. The right choice depends on whether you need to memorise it or not.
| Criteria | Random Password | Passphrase |
|---|---|---|
| Memorability | ✗ Hard to remember | ✓ Easier to memorise |
| Entropy per character | ✓ Very high (6.5 bits) | Moderate (varies) |
| Total entropy at same length | ✓ Higher | Lower per character but long overall |
| Typing speed | ✗ Slow, error-prone | ✓ Faster to type |
| Brute force resistance | ✓ Excellent | ✓ Very good (4+ words) |
| Best use case | Stored in password manager | Master password you type daily |
| Recommended length | 16–32 characters | 4–6 words minimum |
Tips for staying secure
Generating a strong password is just the first step. These habits keep your accounts safe after the fact.
Enable Two-Factor Authentication
Even the strongest password can be phished. Adding a second factor (authenticator app, hardware key) means an attacker needs both your password and physical access to your second factor.
Use a Password Manager
Bitwarden, 1Password, and KeePass let you store hundreds of unique passwords behind one master password. You never have to remember or type your generated passwords manually.
Check for Breaches
Visit haveibeenpwned.com to see if your email has appeared in known data breaches. If it has, change the password for that service and any others where you used the same password.
Change Passwords After a Breach
You don't need to change passwords on a schedule. Change them when a service announces a breach, when you suspect compromise, or if you've been reusing a password and a related account is breached.
Watch Out for Phishing
The strongest password in the world won't protect you if you type it into a fake login page. Always verify the URL before logging in and never click password reset links from unsolicited emails.
Secure Your Recovery Options
Attackers often bypass passwords entirely by exploiting account recovery. Use a strong, unique password for your email account and secure recovery phone numbers and backup codes.
Frequently Asked Questions
Common questions about password generation and security.
Are passwords generated here stored anywhere?▾
No. All password generation happens entirely inside your browser using JavaScript. Nothing is sent to any server. Try2Care has no ability to see, store, or log any password you generate on this page.
What does entropy mean and why does it matter?▾
Entropy measures how many guesses an attacker would need to crack your password, expressed in bits. Each additional bit doubles the number of guesses required. A password with 70 bits of entropy requires 2^70 guesses — over a trillion trillion — which no computer can do in a practical timeframe.
How long should my password be?▾
For most accounts stored in a password manager, 20 characters with mixed types is more than sufficient. For a master password you'll memorise, a 5-word passphrase is an excellent balance of security and memorability. For highly sensitive accounts like banking or email, 24+ characters is recommended.
Is a passphrase as secure as a random password?▾
A 4-word passphrase drawn from a large wordlist has around 50–60 bits of entropy, which is strong. A 5-word passphrase exceeds 70 bits, comparable to a 12-character random password. For a master password you need to type regularly, a passphrase is generally the better choice.
Why are personalised passwords weaker?▾
Personalised passwords based on names, birth years, and common words follow predictable patterns. Attackers build targeted wordlists using data from social media, including names, dates, and personal interests. This tool hardens your inputs, but there is no substitute for a fully random password when security is the priority.
What is the auto-clear feature?▾
When enabled, the auto-clear feature removes the generated password from the screen after 30 seconds. This protects you if you walk away from your device or share your screen, ensuring the password is not left visible. Enable it in the Custom tab settings.
What does "Save Settings" do?▾
Save Settings stores your preferred password length and character type preferences in your browser's localStorage — a storage area that never leaves your device and is not accessible to websites. It allows you to reload the tool later with your preferred configuration already in place.
Can I use generated passwords commercially?▾
Yes. The passwords generated here are random strings produced by your browser. There is no intellectual property concern. Use them for any personal or business account.
