Token Generator

Generate random tokens and strings in hex, alphanumeric, URL-safe, and custom character set formats.

Loading...
1. Select the token format: hexadecimal, alphanumeric, URL-safe, or custom character set. 2. Set the desired token length using the length input or slider. 3. For custom charsets, enter the specific characters to use in the character set field. 4. Click generate to create one or more random tokens instantly. 5. Copy individual tokens or all generated tokens at once using the copy buttons.

About This Tool

Random tokens are essential building blocks in modern software - used for API keys, session identifiers, password reset links, CSRF tokens, invitation codes, and countless other purposes. The Token Generator creates cryptographically secure random strings in a variety of formats including hexadecimal, alphanumeric, URL-safe, and custom character sets with configurable length.

The tool uses the Web Crypto API to ensure genuine cryptographic randomness rather than pseudorandom number generation. This means the tokens are suitable for security-sensitive purposes where unpredictability is critical. You can generate individual tokens or bulk-generate multiple tokens at once, with options to add prefixes, separators, or format the output as a list or array.

Whether you are building an API that needs to issue access tokens, creating unique identifiers for database records, generating secure invitation links, or producing random test data, this tool gives you full control over token format and length. All generation happens in your browser with no server communication, so your tokens remain private from the moment they are created.

Frequently Asked Questions

Yes. The tool uses the Web Crypto API (crypto.getRandomValues) to generate tokens with true cryptographic randomness. These tokens are suitable for security-sensitive purposes like API keys, session tokens, and CSRF protection.
Hexadecimal is standard for session IDs and hash-like tokens. Alphanumeric works well for invitation codes and short identifiers. URL-safe (Base64url) is ideal for tokens embedded in URLs. Choose based on where and how the token will be used.
For security tokens like API keys and session IDs, use at least 32 characters (128 bits of entropy) in hexadecimal or 22 characters in Base64. For non-security purposes like short codes, 8-12 characters may suffice depending on your collision tolerance.
No. All token generation runs entirely in your browser using the Web Crypto API. No tokens, settings, or data are transmitted to any server.
UUIDs follow a specific format (8-4-4-4-12 hex digits) and standard (v4 or v7). The Token Generator offers fully customizable length, character sets, and formats. Use UUIDs when you need standard-format identifiers and tokens when you need flexible random strings.
