Credentials (n8n)
In n8n, credentials are securely stored authentication details (API keys, OAuth tokens) that nodes reuse to connect to services.
Analogy
Like a saved password vault your workflows draw from without re-typing.
Why it matters
Centralized, encrypted credentials let you authenticate nodes safely without hardcoding secrets in workflows.
In practice
Saving a GoHighLevel API credential once and reusing it across many nodes.
