Welcome back to another critical security episode in our massive n8n workflow automation series! When you are building automations, you are constantly connecting to dozens of different apps—OpenAI, Slack, Google Sheets, Postgres—and every single one of those requires saving an API key or OAuth token inside n8n. But what happens when a client leaves, a key expires, or you accidentally save a production token in a testing environment? Leaving old, unused API keys lying around is a massive security risk! In this fully updated 2026 comprehensive tech tutorial, we are going to show you exactly how to delete stored credentials in n8n, manage your API connections, and keep your self-hosted server completely secure!
In the first section of this complete video guide, we will tackle the core of n8n's security: The Credentials Manager. We will walk you through the n8n UI, showing you how to navigate away from the workflow canvas and open the dedicated "Credentials" tab on the left-hand menu. You will learn how to browse through your global list of stored API keys, OAuth connections, and database passwords. We will show you the exact UI mechanics to safely remove them: locating the specific credential, clicking the "more options" (three dots) button, selecting "Delete," and confirming the permanent removal!
Next, we take a deep dive into credential dependencies and workflow troubleshooting. Before you hit delete, you need to know if that API key is currently being used! We will show you how to check which specific workflows are tied to a credential. If you delete a credential that an active workflow relies on, that automation will immediately crash the next time it runs! You will learn best practices for swapping out old API keys for new ones directly inside the node settings before you delete the legacy credential from the global manager.
Moving into the second half of our tutorial, we will explore advanced credential management for agency owners and enterprise teams. We will discuss the crucial security benefits of regularly pruning your unused access points. Finally, for DevOps engineers managing complex deployments, we will touch upon how credential deletion is handled at the database level (SQLite vs. PostgreSQL) to ensure no trace of your sensitive data remains on the server.
Mastering how to manage and securely delete stored credentials in n8n is the ultimate key to maintaining a zero-trust, perfectly organized, and highly secure automation environment!
