wandb login

CLI reference for the wandb login command, which authenticates with the W&B server using an API key.

Verify and store your API key for authentication with W&B services.

By default, only store credentials locally without verifying them with W&B. To verify credentials, set --verify=True.

For server deployments (dedicated cloud or customer-managed instances), specify the host URL using the --host flag. You can also set environment variables WANDB_BASE_URL and WANDB_API_KEY instead of running the login command with host parameters.
