FAQ

Questions about the Secret Scanner

Which key types does the scanner detect?

AWS access key IDs, GitHub tokens, OpenAI-style sk- keys, Slack tokens, private key blocks, JWTs, Mailchimp keys, Google API keys and generic secret, api, token or key assignments with a long quoted value.

What should I do if a secret was already committed to Git?

Rotate or revoke the key with the provider first, because deleting it from the latest commit does not remove it from history. Then clean the history if needed and add a pre-commit secret scan.

Can a pattern scanner miss secrets?

Yes. It only finds formats it has rules for, so custom tokens or passwords without a recognisable shape can slip through. Use it as a quick first check alongside a full repository scanner.

Is the Secret Scanner free and private?

Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
