32 character strings are commonly used for API keys, authentication tokens, session IDs, and encryption secrets. Generate cryptographically secure random strings instantly — perfect for development and server configuration.
API keys, database passwords, JWT secrets, webhook signing keys, and encryption keys typically need 32+ characters. This generator provides the randomness these security-critical values demand.

How to Generate 32 Character Password — For API Keys & Tokens
- Open the Password Generator tool
- Set length to 32 characters
- For API keys: use alphanumeric only (no symbols that need URL-encoding)
- For secrets: enable all character types for maximum entropy
- Click "Generate Password"
- Copy directly into your .env file or secrets manager
Pro Tips
- For JWT secrets: use 32+ chars with all types for 256+ bits of entropy
- For API keys: alphanumeric only avoids URL-encoding issues
- Store secrets in environment variables, never in source code
- Rotate API keys and tokens every 90 days as best practice
Frequently Asked Questions
Why do API keys need 32 characters?
32 alphanumeric characters provide ~190 bits of entropy — enough to make brute-force and rainbow table attacks computationally impossible.
Should API keys include symbols?
Generally no. API keys often appear in URLs, headers, and config files where symbols need escaping. Alphanumeric (A-Z, a-z, 0-9) is standard for keys and tokens.
How many bits of entropy is a 32-char password?
With full character set (95 chars): ~210 bits. Alphanumeric only (62 chars): ~190 bits. Both are far beyond the 128-bit minimum for cryptographic security.
Can I use this for encryption keys?
For general secrets (JWT, HMAC, API), yes. For AES encryption keys specifically, you need exactly 16/24/32 bytes of raw entropy — use a proper key derivation function (PBKDF2, scrypt).
