Token Generator
Generate cryptographically secure random tokens for API keys, session IDs, webhook secrets, and development environments. Everything runs locally in your browser.
Generate a secure token
Generated tokens
Choose your settings and generate a token.
Why use this secure token generator?
It is designed for machine-consumed secrets rather than memorable account passwords.
How to generate a random token
Choose a format
Use random characters for flexible secrets, Hex for byte-oriented systems, or Base64URL for URLs and headers.
Set length and count
Pick the displayed character length and how many independent tokens you need.
Review the entropy
Use the live estimate to confirm that the effective alphabet and length fit your security needs.
Generate and store safely
Copy the result into a secret manager or protected environment variable, not source control.
Common token generator use cases
API keys
Provision unpredictable credentials for internal APIs, prototypes, and test integrations.
Session and reset tokens
Create high-entropy examples for authentication and password-reset flows.
Webhook secrets
Generate shared secrets for verifying webhook signatures.
Test fixtures
Produce IDs and secret-shaped sample data without reusing real credentials.
How secure token generation works
The generator reads cryptographically secure random values from crypto.getRandomValues(). Rejection sampling prevents modulo bias when bytes are mapped to a custom alphabet.
Length, alphabet, and entropy
Estimated entropy is length × log2(alphabet size). A larger alphabet and longer token increase the number of possible values.
Production storage matters
Generation is only the first step. Store production secrets in a dedicated secret manager, rotate them, limit access, and never commit them to Git.
Token generator troubleshooting
Nothing is generated
Enable at least one character group or enter at least one custom character.
A service rejects symbols
Select Base64URL, Hex, or disable symbols to meet the service's accepted alphabet.
The token has the wrong size
Length is the displayed character count, not the decoded byte count.
Clipboard access fails
Browser permissions may block automatic copying; select the token text and copy it manually.
Token Generator FAQ
What is a random token?
A random token is an unpredictable string used as an API credential, session identifier, reset code, or application secret.
Is this token generator cryptographically secure?
Yes. It uses crypto.getRandomValues() rather than Math.random() and avoids biased character mapping.
What token length should I use?
Choose according to your system's threat model. At least 128 bits of entropy is a common baseline for long random secrets.
Should I choose Hex or Base64URL?
Hex is simple and widely accepted but uses two characters per byte. Base64URL is more compact and safe in URLs and HTTP headers.
Are generated tokens uploaded or stored?
No. Generation happens locally in browser memory and this page does not save the results.
Is a token generator the same as a password generator?
No. Tokens are normally copied and consumed by software, while passwords may need to satisfy account rules or be memorable to people.
