Why cookies are not saved in WosdPress?

Question

HTTP Cookies

Hello.
When I am logged into my account, then go to any post and go back to the main page, I somehow log out of my account, and when I reload the site, I am already logged into my account.
Another case: when I am authorized on the site, I close the browser for 2-3 minutes, when I open the browser and go to my site, I log out of my account.
Why is this happening?

Answer 1

Am I the only one who didn't understand?
