How do I change or regenerate my API key?
1 min read · Last updated June 2026
To replace your master key, regenerate it. The old key stops working immediately, so update it everywhere you use it. Sub-keys cannot be regenerated, so to replace one you delete it and create a new sub-key.
Regenerate your master key
The Regenerate button is on both the Dashboard overview and the API keys page.
- Sign in and open Dashboard, or API keys for the fuller view.
- On the master key, click Regenerate and confirm.
- Copy the new key (it starts with
sk_live_).
Update it in the plugin
- In WordPress, go to Media > SlashImage.
- Paste the new key into the key field and click Reconnect.
- Confirm the connection pill reads Connected.
If you use the key on more than one site, update it on each one. Optimizing resumes on a site as soon as it has the new key.
Replace a sub-key
Sub-keys can't be regenerated. To replace one, open API keys, click Revoke on the old sub-key, then create a new one. Copy the new sk_sub_ key and connect it on the site that used the old key. See What are sub-keys and how do I create them?.
