From past few days brave is just logging me out from most of the sites when I reopen the browser. Any help on how to fix it?
Go to brave://settings/clearBrowserData and make sure nothing in the On Exit tab is checked.
Go to brave://settings/shields. See if Forget me when I close this site setting is there. If it is, it’ll be below Block cookies. If the option is available for you, make sure it’s turned off.
If neither of these apply to you, it’s likely an extension causing this behavior.
In addition to what u/yokoffing posted, check your settings on brave://settings/content/siteData
You can default to allow site data, delete site data on close, or don’t allow site data.
Below those options you can set per-site exceptions. These settings don’t sync with the Forget Me shields.
