Let me give you a clear plan. **What's happening:** The `ValueError: Invalid decryption key` means the `SECRET_KEY` currently in use doesn't match the key that was used when your database connection credentials were originally saved. Superset uses the `SECRET_KEY` to encrypt/decrypt stored passwords, so mixing keys between your instance and your friend's instance has scrambled things [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). **Step-by-step fix:** **1. Figure out which key is actually being loaded** Open a terminal in your Superset folder and check: ```cmd echo %SUPERSET_SECRET_KEY% ``` If that prints anything, it's overriding your `superset_config.py` [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). Also open your `superset_config.py` and make sure the `SECRET_KEY` value is exactly what it was when you first set up *your* instance — no extra spaces, no newline at the end. Superset logs which config file it loads on startup — look for `Loaded your LOCAL configuration at [...]` in your startup output to confirm it's picking up the right file [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). **2. Pick ONE key and stick with it** Your metadata database was encrypted with one specific key. You need to use that same key every time. **Never swap keys between restarts** without re-encrypting. **3. Re-create your database connections** Once you have the correct key loaded and Superset starts without errors, go to **Settings → Database Connections** and delete and re-add any broken connections. The stored passwords were encrypted with the wrong key and can't be recovered without the original — but you can just re-enter them [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). **4. If you need to switch to a new key** Superset has a CLI command for key rotation: ```bash superset re-encrypt-secrets ``` This re-encrypts stored credentials with the new key. Run it while the old key is still active, then swap to the new key [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). **5. Clear your browser session** After fixing the key, clear cookies/local storage for `127.0.0.1:8088` in your browser and log in fresh — stale session cookies from the old key will cause login failures even if the backend is correct [[1]](https://github.com/apache/superset/discussions/43153#discussioncomment-18012451). The most important thing: **identify the original key your metadata DB was encrypted with and restore it.** If that was your own key before you cloned your friend's project, go back to that value in your `superset_config.py`. Let me know what you see in step 1 and we can narrow it down further! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Docs are dead.
