What is the difference between a token and a password?

Passwords are created by users and meant to be memorized, while tokens are randomly generated strings used by applications for authentication. Tokens are typically longer, more random, and used for machine-to-machine communication.

What formats of tokens can I generate?

Our tool generates tokens in multiple formats: hexadecimal (0-9, a-f), alphanumeric (letters and numbers), base64 (URL-safe encoding), and custom character sets. You can also specify the exact length you need.

Are the generated tokens secure?

Yes, tokens are generated using cryptographically secure random number generation in your browser. They are never transmitted to our servers, ensuring complete privacy and security.

What are common uses for generated tokens?

Generated tokens are commonly used for API keys, access tokens, session identifiers, CSRF tokens, password reset links, email verification codes, webhook secrets, and any application requiring secure random strings.

Q: What is a token generator?

A token generator creates random strings of characters used for authentication, API keys, session tokens, and other security purposes. These tokens are designed to be unique, unpredictable, and difficult to guess.

What is a Token Generator?

A token generator creates random, unique strings used for authentication, session management, API keys, and secure identifiers. Unlike passwords meant for human memory, tokens are designed to be long, random, and machine-readable. Our free online token generator uses cryptographically secure random number generation to create tokens that are virtually impossible to predict or brute force. Tokens are essential in modern web development for securing APIs, managing user sessions, implementing OAuth flows, and creating unique identifiers for database records. Whether you need hexadecimal strings, alphanumeric tokens, URL-safe Base64, or standard UUIDs, this tool generates them instantly in your browser.

How to Use This Token Generator?

1

Choose Token Format

Select Hexadecimal for session IDs, Alphanumeric for API keys, Base64 for URL-safe tokens, or UUID for standard unique identifiers.

2

Set Token Length

Use the slider to set length from 8 to 256 characters. Longer tokens provide more entropy and security.

3

Add Prefix/Suffix

Optionally add prefixes like "sk_" or "api_" to identify token types, following patterns used by services like Stripe.

4

Generate & Copy

Click Generate for a single token or "Generate 5" for bulk generation. Copy tokens with one click.

Common Questions

Free Online Token Generator Tool

Our free online token generator is an essential tool for developers, security professionals, and anyone who needs cryptographically secure random tokens. Whether you're building APIs, implementing authentication systems, or generating unique identifiers, this tool provides instant, secure token generation directly in your browser.

The generator supports four formats: Hexadecimal tokens (using 0-9 and a-f) are perfect for session IDs and cryptographic hashes. Alphanumeric tokens combine letters and numbers for readable API keys. Base64 tokens are URL-safe and compact. UUID v4 tokens follow the RFC 4122 standard for globally unique identifiers. Each token is generated using the Web Crypto API for true cryptographic randomness.

All generation happens client-side—your tokens never leave your browser, ensuring complete privacy. For secure passwords, try our password generator. Explore our full utility tools collection for more development helpers.
