About API Key Generator — Free Online Tool
API Key Generator produces keys in the prefix_random shape modern APIs use: a label you choose, an underscore, then a base62 random string.
The random part is base62 and comes from crypto.getRandomValues, at any length between 16 and 128 characters, and up to 50 keys can be produced in one pass. The prefix is the genuinely useful half of the convention — a value starting sk_live_ is recognisable in a log, a paste or a committed file, which is how automated secret scanners catch a leak before anyone exploits it. What comes out is a random string and nothing more: it is registered with no service, so issuing one means storing it yourself, as a hash, and showing the plaintext to its owner exactly once.
Keys are generated on your device and never leave it, so a secret you intend to put into production exists only on your screen and in your clipboard.
Issuing a key for an API you run, creating a webhook signing secret, generating service credentials for a staging environment, and seeding a key table in development.
Also known as: generate api key · api token generator · secret key maker · webhook secret generator
When to use it
Standardize API token issuance for SaaS platforms, webhook endpoints, and microservice authentication.
How it works
Generates 256 bits of CSPRNG entropy and encodes as base62/base58/hex string with custom prefixes.
Why Prefixes Matter
Prefixes (e.g. omni_live_) allow automated secret scanners (like GitHub Secret Scanning) to prevent leaks.
