Random Token Generator

What is a Random Token Generator?

A random token generator creates cryptographically secure random strings of characters used for authentication, security, and identification. Whether you need API keys, session tokens, JWT secrets, OAuth credentials, or unique identifiers, our generator produces truly random tokens using your browser's native cryptography APIs. All generation happens locally with zero server involvement, ensuring complete privacy.

How to Use the Token Generator

Step 1: Click a preset (UUID, 32-char Hex, 64-char Base64, or JWT Secret) or customize the token length from 8 to 512 characters.
Step 2: Choose your character set—hexadecimal, Base64, alphanumeric, or with special symbols. Alternatively, provide your own custom characters.
Step 3: Set the number of tokens to generate (1–100).
Step 4: Apply formatting like UUID-style hyphens every 4 characters or convert to uppercase.
Step 5: Click "Generate Tokens" and copy individual tokens, all at once, or download as a text file.

Common Use Cases

API Keys & Secrets: Generate secure API keys for third-party integrations and services.
Session & Auth Tokens: Create unique session identifiers and authentication tokens for user login systems.
OAuth & JWT: Build secure OAuth tokens, refresh tokens, and JWT signing keys.
Database Identifiers: Generate random primary keys and unique IDs for database records.
Security Codes: Create one-time passwords, verification codes, nonces, and CSRF tokens.
Encryption Keys: Use as initialization vectors or encryption key material.

Frequently Asked Questions

Are these tokens truly random and cryptographically secure?

Yes. The generator uses the Web Cryptography API's crypto.getRandomValues() to produce cryptographically secure random bytes. All generation is done in your browser with no server involvement, so your tokens remain completely private.

Can I use a custom character set?

Absolutely. Select "Custom Characters" and enter any characters you want the generator to randomly select from. For example, enter "ABC123" to generate tokens using only those characters.

What's the difference between the preset options?

UUID: 32 hexadecimal characters formatted with hyphens (8-4-4-4-12)—standard UUID v4 format.
32-char Hex: 32 hexadecimal characters, useful for MD5-like hash representations.
64-char Base64: 64 Base64-encoded characters, ideal for API keys and authentication secrets.
JWT Secret: 256 Base64 characters suitable for signing and verifying JSON Web Tokens.

Why is the maximum 100 tokens per generation?

Limiting to 100 tokens per batch ensures the tool remains responsive in your browser. You can generate multiple batches and combine them if you need more tokens.

Is my data stored or transmitted anywhere?

No. All token generation happens entirely in your browser using JavaScript. Nothing is sent to our servers, and we don't store, log, or track any tokens you generate. Your privacy is guaranteed.

What's the difference between "No separator" and "UUID format"?

"No separator" produces a continuous string like a1b2c3d4e5f6. "UUID format" inserts hyphens every 4 characters, like a1b2-c3d4-e5f6-g7h8, for improved readability.
