Being logged out of all web accounts in cycle

Hello,

In the past few weeks, I've noticed that, every few days, I am being logged out of all of my web accounts in a cycle of some amount of days. Every account you can name. (Google, Ancestry, FindAGrave, etc.)

I haven't changed any settings, and I have not updated to macOS Sequoia yet (still on MacOS Sonoma 14.5 out of pure procrastination). I am on the Safari browser, using a 2022 MacBook Air.

Does anybody know why this could be?

Regards,
