Cobaltmetrics uses API keys to identify users and their privileges. API keys do not expire, and each user can create up to 5 keys.
Please note that API keys must be saved locally before you navigate to another page or log out of Cobaltmetrics. To save a new API key, click the clipboard icon to copy the key to your clipboard, and store it securely on your device. If you lose access to any of your API keys, you must delete it and create a new one.
