When you deactivate your account, no one will be able to view or visit your Facebook profile. Your photos, messages, and videos will not be deleted. You will continue to appear to friends on Facebook in places where they can contact you as if nothing happened.
Since your privacy settings don’t change before or after deactivating and reactivating your account, it’s open to the same people on your friends list as it was when you clicked “Deactivate your account.” In the end, there is no method to reactivate your account without revealing that you’ve returned.
When users deactivate their accounts, they “disappear.” They no longer appear on others’ friend lists or friends can’t “unfriend” them. Furthermore, as the study points out, “Facebook does not notify its users when their friends are activated or deactivated.”
You may hide your profile from specific users or make it invisible to everyone except friends or friends of friends, depending on your requirements. If you only want to conceal your profile after you’ve logged out, you can do so by deactivating your account.
If you don’t want to go through the trouble of completely deleting your Facebook account (I know how many memories you have), then you may deactivate it for a short time. It’s called the “super-logoff,” and it was a technical trick employed by early privacy-conscious users when they quit the site.
