ssambhi,

Understood, thank you.

To help narrow this down further, can you also let us know if you experience the same issue when using a private window in Safari? More about browsing privately here: Use Private Browsing in Safari on Mac

Also, do you experience the same behavior in safe mode? If the issue doesn't happen in safe mode, the "If the issue doesn't continue in safe mode" section of this page explains what to do: How to use safe mode on your Mac

Thanks!

ssambhi,

Thanks for letting us know more about what you're experiencing.

Just to clarify, do any messages or errors appear before you're logged out of those websites? If so, what does the error say?

You mentioned that this started a few months ago; were any changes made to your device or its settings before this began?

If Safari isn't working as expected on your Mac, the information and steps here may help: If Safari on Mac doesn't open a webpage or isn’t working as expected

Take care!

Hey there, ssambhi! 

Thank you for posting in Apple Support Communities.

When this happens, does it log you out of just the sites or does it log you out of the computer? Also, does this happen when the sites are actively in use?

If it completely logs you out of the computer, check out the information here to make that stop: Set your Mac to log out when not in use - Apple Support

Kindest regards.
