Generate secure, random 32-character passwords. 211 bits of entropy — overkill strength. Everything runs in your browser.
Use ⌘ + D to bookmark this toolA 32-character password provides 211 bits of entropy — far beyond what any brute-force attack could ever reach, even with theoretical quantum computers. At this length, you're generating a cryptographic-grade secret. The crack time exceeds the expected lifespan of the universe by a factor of 10³⁵. This is used when security must be absolute and memorability is irrelevant.
Entropy is calculated as: length × log₂(pool_size). With 32 characters from the full 95-char printable ASCII set, you get 211 bits of entropy. Brute-force time at 10 billion guesses/sec: 4 × 10⁴⁵ years.
50 pre-generated examples. Use the generator above for a cryptographically fresh password — these are for illustration only.
HMAC-SHA256 signing keys should be at least 32 bytes (256 bits). JWT HS256 secrets require minimum 32 characters. Stripe API keys are 32 characters. AWS secret access keys are 40 characters. Most API key standards recommend 32+ character secrets.
HMAC keys for webhook verification (Stripe, GitHub, Slack), JWT signing secrets, and API authentication tokens. These secrets authenticate millions of requests and must never be compromised.
AES-256 encryption keys for data at rest. S3 bucket encryption, database field encryption, and file-level encryption all benefit from 32-character key material.
Machine-to-machine authentication tokens in microservice architectures. These credentials are stored in secret managers and never typed by humans.
Validator node authentication, staking keys, and consensus participation credentials. Compromised validator keys can lead to slashing penalties worth millions.

Yes. A 32-character password using uppercase, lowercase, numbers, and symbols provides 211 bits of entropy — well beyond what brute-force attacks can crack. It would take 4 × 10⁴⁵ years to break with current GPU technology.
With a modern GPU cluster computing 10 billion hashes per second, a random 32-character password using all character types (95-char pool) would take approximately 4 × 10⁴⁵ years to crack by brute force. Using only lowercase letters would be significantly faster to crack.
Both matter, but length has a greater impact. Each additional character multiplies the total combinations by the pool size (up to 95 for all printable ASCII). However, using all character types (uppercase, lowercase, numbers, symbols) maximizes the pool size, which also multiplies security exponentially.
Yes. You cannot reliably memorize unique random passwords for every account. A password manager securely stores all your passwords behind one strong master password, and can auto-fill them across devices and browsers.
A 32-character password is recommended for: encryption keys, signing secrets, and long-lived API tokens. Always use the strongest password practical for each account, and never reuse passwords across sites.
