Safari losing cookies / login data of websites

Hello and welcome to Apple Support Communities, medialp,

If we understand your post correctly, cookies don't seem to be save in Safari on your MacBook Pro. Cookies can certainly make it faster and easier to log in to websites. We’d like to help.

There are several reasons this may be happening. If you've recently cleared your browsing history, changed any settings, or changed networks or routers. You may also experience this if a website has updated or changed their log in page.

To check your settings and make sure cookies are saved when you want to be check out this guide:

Manage cookies and website data in Safari on Mac - Apple Support

Let us know if that resolves this issue for you.

Thanks for using the Apple Support Communities.
