Can someone hack my Facebook account if they have my email address?
It is not possible to hack your Facebook account solely by having your email address. However, if someone has access to your email account and your Facebook account is linked to that email address, they may be able to gain access to your Facebook account by resetting your password. To prevent this, make sure your email account is also secured with a strong, unique password and consider enabling two-factor authentication for both your email and Facebook accounts.
