Limited access mode
From The GPRO Wiki
This account mode allows you to set a separate limited access password, which can be particularly useful if you plan to use any tools for data gathering. When a tool uses the limited access password it will have read only access to your account and will not have access to any sensitive account data. You can set a limited access password from the Account settings page.
Why does my account show "Limited access mode"?
Because you have used your limited access password to login to the site. Use your main password to login and everything will be as usual.
