Rotating OKX API keys on a schedule without breaking your tools

An API key that has been active for a long time has had more opportunities to leak: through a tool provider's breach, a forgotten configuration file, an old backup or a laptop you sold. Rotating keys, replacing them with new ones on a schedule, limits how long any leaked key remains useful. Many people avoid it because they fear breaking an integration that works. With a simple routine, rotation becomes a five-minute task with no downtime. This guide explains how to plan rotation for OKX API keys, how to switch each tool to a new key safely, how to confirm everything works and how to remove the old key promptly. It also suggests how often to rotate depending on what each key can do.

Decide how often each key should rotate

Not every key carries the same risk. A read-only key for a portfolio tracker could reasonably be rotated every few months. A key with trading permission for an automated tool deserves more frequent rotation and closer monitoring. Keys should never have withdrawal permission unless strictly necessary, and if one does, treat it as high risk. Write down a rotation schedule for each key alongside its purpose, and add reminders to your calendar so the task does not depend on memory.

Create the replacement before removing the old key

When a key is due, create a new one in OKX with the same narrow permissions and IP restrictions as the current key, and a label that includes the tool name and the new date. Store the new secret and passphrase in your password manager. Then update the tool's settings to use the new key. Keeping the old key active for these few minutes ensures there is no gap. Avoid creating the new key with broader permissions just to make the switch easier.

Confirm the tool works, then delete the old key

After updating the tool, check that it can read data or place orders as expected. Look at the tool's own status or logs and, if it trades, confirm a recent action appears in your OKX history. Once satisfied, delete the old key in OKX straight away. Do not leave it as a backup; a forgotten old key is exactly the risk rotation is meant to remove. Update your notes with the new creation date.

Use rotation time for a wider review

Each rotation is a good moment to review all keys on the account. Delete any that belong to tools you no longer use, check that IP restrictions are still accurate if the tool's servers changed, and look at recent login and security activity for anything unusual. If you find a key you do not recognise, treat it as a possible compromise: delete it, change your password and contact OKX support through the app.

Scenario checkpoint

• Set a rotation schedule for each OKX API key based on its permissions and add calendar reminders.
• Create the replacement key with the same narrow permissions and IP restrictions before touching the old one.
• Confirm the tool works with the new key, then delete the old key immediately rather than keeping it as backup.
• Use each rotation to remove unused keys and investigate any key you do not recognise.
