It’s a good idea to deactivate or delete your account when you stop using a social networking profile or website. This means that your material will no longer be displayed online and will no longer be searchable. It also eliminates the possibility of these accounts being hacked or utilized by others without your knowledge.
On Facebook you have the options of either Deactivating And Deleting Your Account.
If you deactivate your account:
- You can reactivate it whenever you want. (This will mean you can access your photos, videos, friends and groups again).
- People can’t see your timeline or find your account in a search unless you reactivate the account.
- Some things may remain visible (for example: private messages you have sent).
- You can reactivate your account at any time by logging back into Facebook or by using your Facebook account to log in somewhere else. You’ll need to have access to the email or mobile number you use to log in to complete the reactivation.
To deactivate your account:
- Click in the top right of Facebook.
- Select Settings & Privacy > Settings.
- Click Your Facebook Information in the left column.
