Token Length
Token Use Cases
API Keys
Generate secure keys for API access control. Long complex tokens prevent unauthorized access to your services.
User Passwords
Create strong passwords with mixed character types to protect user accounts against brute-force attacks.
Security Tokens
Produce authentication tokens like OTPs and session tokens that are cryptographically secure and unpredictable.
Frequently Asked Questions
Is this token generator secure?
Yes, our token generator uses the browser's built-in cryptographic API (window.crypto.getRandomValues) to create truly random strings. All processing happens locally in your browser with no server-side involvement.
What token length should I use?
For most applications, we recommend at least 32 characters. High-security scenarios (like encryption keys) should use 64+ characters. The default 128-character length provides maximum security.
Why exclude similar characters?
Excluding lookalike characters (0/O, 1/l/I) prevents confusion during manual entry. Enable this option when tokens need to be typed by users.
Are generated tokens stored?
No, all tokens are generated locally in your browser. They are never sent to any server and disappear when you refresh the page.
Does this work on mobile devices?
Yes, our token creator is fully responsive and works perfectly on smartphones, tablets, and desktop devices.
Token Security Best Practices
Rotate Tokens Regularly
Change security tokens every 3-6 months for high-risk applications to minimize exposure from potential breaches.
Apply Least Privilege
Assign minimal required permissions to each token to limit potential damage if compromised.
Secure Storage
Never hardcode tokens in source files. Use environment variables or dedicated secrets management solutions.
