Token generator

Token generator. Generate random string with the chars you want, uppercase or lowercase letters, numbers and/or symbols. Instantly create secure random strings with our free online token generator.

This essential cybersecurity and backend development tool allows you to rapidly generate cryptographically secure alphanumeric tokens, API keys, and session identifiers.

Whether you are a software engineer assigning access tokens for OAuth2 authorization flows, a systems administrator generating secure WiFi passwords, or a QA tester mocking user session IDs, our random string generator provides configurable length and character sets.

If you need to evaluate the strength of your generated tokens, our Password Strength Analyser is the perfect companion utility. Simply define your desired length, select your character constraints, and generate your secure tokens instantly.

This premium secure token generation utility leverages advanced Cryptographically Secure Pseudorandom Number Generators (CSPRNG) to compute your strings directly within your browser, ensuring that your highly sensitive API keys and session tokens are never transmitted over a network or uploaded to a remote server.

Generating access tokens on third-party remote servers completely compromises their cryptographic integrity, but our entirely offline tool eliminates this vulnerability, making secure key creation a 100% private and trustless workflow.

We provide a 100% free, private, and secure way to generate alphanumeric tokens locally on your device.

How to use this online tool

Token generator is designed for fast browser workflows when you need to format, validate, convert, decode, encode, generate, or inspect data without opening a heavy desktop app. Start with the input field or visible options, review the result, then copy or download the output for the next step.

Private processing in your browser

Token generator keeps the normal processing step local in your browser. That is useful for code snippets, tokens, documents, configuration values, text samples, and other material that should not be sent to a remote service unless you explicitly choose to share it.

When this tool is useful

Use Token generator for repeatable developer tasks, technical documentation, QA checks, quick conversions, debugging, content cleanup, and internal team workflows. The page focuses on clear inputs, immediate feedback, and output that is easy to reuse in code, reports, tickets, emails, or notes.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
