Generate a Weights & Biases API key
A Weights & Biases API key authenticates requests against the W\&B GraphQL Public API on behalf of your account. The key inherits the full permissions of the user who mints it — W\&B keys have no scopes, permission picker, or expiration.
Go to the W\&B sign-in page and complete Log In. You can sign in with Sign in with Apple, Sign in with GitHub, Sign in with Google, Sign in with Microsoft, or with your email and password using the Email and Password fields.
- Don't have an account? Use the Sign up tab on the same screen, or open app.wandb.ai/login?signup=true.
Once signed in, click your profile avatar in the top-right corner to open the Toggle profile & account menu, then click API keys in the Account section of the dropdown. This lands you on the API keys panel of User settings (`https://wandb.ai/settings#apikeys`) where every key on your account is listed.
In the API keys panel click + New key to open the Create new API key dialog. On Step 1 of 2 : Configure key, optionally enter a value in the Name (optional) field (the default is Untitled Key), then click Create API key to advance to Step 2.
- Choose a descriptive name — the name appears in the API keys list so you can identify which key is used by StackOne when it's time to rotate or revoke it.
On Step 2 the Your new API key dialog appears with the freshly minted key. Click Copy next to the API KEY value to copy the key to your clipboard, or click Copy and close to copy and dismiss the dialog in one step.
- The dialog displays this warning in red: SAVE THIS KEY NOW. This is the only time you'll see the complete key. The full key is displayed once and cannot be retrieved later.
- Under Key information you can see the Key ID, Name, Created date, and Owner — StackOne only needs the value that is copied by the Copy button, not the Key ID.
- Store the copied key in a secure location. If you lose it, open the API keys section again and use + New key to mint a replacement — the old key cannot be retrieved.
In StackOne Hub, paste the copied value into the W\&B API Key field. StackOne sends it as a bearer token on every request to the W\&B GraphQL Public API at `https://api.wandb.ai`.
- W\&B API Key — the value you copied from the Your new API key dialog (starts with `wandb_v1_`). The key grants full access to your W\&B account and should be kept secure.
- W\&B API keys have no scopes, permission picker, or expiration — a key inherits the full permissions of the user who minted it, so admin-only operations require an admin account.
- To manage existing keys later, open the avatar menu → API keys; from there you can search by name or key ID, mint another + New key, or revoke keys you no longer need.
