In Privacy Checkup, click through the cards on the screen to adjust your privacy settings.

Set the audience of any information you share on Facebook to Friends. But for the highest security setting, set the audience to Only Me.

Use Instagram’s Restrict function if you are receiving unwanted contact from a follower but do not feel comfortable blocking them. This will limit your interactions with that user. You will not be notified if they comment on your post or message you. Any comment of theirs will have to be approved by you before they are publicily viewable, and any messages from them will go into your Message Requests. Instagram does not inform the user if you have restricted them, and they will not be able to see when you’re online or when you have read their messages.

To restrict a user, go to their profile

• Click on the three dots () in the top-right corner.
• Click Restrict

You can also restrict users by going to Settings > Privacy > Restricted Accounts, then typing the username of the user into the search bar, and selecting Restrict

Turn on two-factor authentication to add a layer of security in case someone tries to hack into your account. When you turn on two-factor authentication, Instagram will ask for a six-digit code in addition to your password when logging into your account.

• Go to Settings > Security > Two-factor authentication
• Choose whether you’d like to receive the six-digit code via your phone number or an authentication app on your phone, and follow the instructions on the screen to set this up.
• Then go to Additional methods and turn on Login requests. This means that Instagram will send you a notification to approve new devices that try to log into your account.

Your public profile is visible to anyone on the internet. It is also indexed on search engines. Where possible, we encourage you to limit the amount of information shared on your public profile.

• Log into LinkedIn
• Click the Me icon at the top-right corner of your LinkedIn homepage
• Select Settings & Privacy from the dropdown
• Select Visibility
• Select Edit your public profile
• Under Edit Visibility, turn off your profile’s public visibility for the highest security setting. This means that only those who have signed into LinkedIn are able to view your profile, and your profile will remain open to recruiters who are signed into LinkedIn.

You may also want to limit your profile visibility on third-party apps such as Outlook. To do so

• Go to Settings & Privacy > Visibility
• Click Profile visibility off LinkedIn
• Set Should we show information from your profile to users of permitted services such as Outlook to No

People can also search for you on LinkedIn using your email address and phone number. Follow the steps below to prevent this.

• Under Visibility (in Settings and Privacy), set
  • Profile discovery using email address to Nobody for the highest security setting
  • Profile discovery using phone number to Nobody for the highest security setting

By default, the primary email address that you use for your LinkedIn account is visible to your direct connections. For the highest level of security, you will want to make your email address visible only to you.

• In Visibility > Who can see or download your email address
  • Set Who can see [your email address] on your profile or in approved apps to Only visible to me
  • Set Allow your connections to download your email in their data export to No

If you want to remain contactable for professional reasons, but have signed up for LinkedIn using your primary/personal email address, consider using your work email address or creating a separate email address for professional use. To register a new email address as your primary address on LinkedIn:

• Go to Settings & Privacy > Sign-in & Security
• Select Email addresses > Add email address
• Type the email address that you want to add, then click Send Verification
• Enter your LinkedIn password when prompted.
• LinkedIn will send a verification email to this new address. Go to the inbox for the email address that you have added to find this email, and click on the verification link.
• Once this is done, go back to Settings & Privacy > Sign-in & Security > Email addresses and click Make primary to make your new email address your primary address on LinkedIn.
• You can then choose whether you want to remove your previous email address from LinkedIn. To do so, click Remove next to the address, and enter your LinkedIn password when prompted.

By default, your last name is visible to anyone who isn’t a connection on LinkedIn. For the highest level of security, abbreviate your last name. To do so

• Go to Settings & Privacy > Visibility
• Click Who can see your last name and select the abbreviated option.

Finally, you may want to decide whether your connections are notified when you’re mentioned in an article or blog post. You may want to turn this off if if you are facing targeted harassment or defamation. To disable notifications,

• Go to Settings & Privacy > Visibility
• Click Notify connections when you're in the news
• Set Should we notify your connections and followers when you’re mentioned in the news? to No

You may also want to disallow others from mentioning or tagging you in content posted on LinkedIn. To do so

• Go to Settings & Privacy > Visibility
• Click Mentions or Tags
• Set Allow others to mention or tag you in content posted on LinkedIn to No

You can control who gets to see your LinkedIn connections. This will prevent harassers/abusers from contacting your professional network, especially if they are trying to defame you or capture your attention.

• Log into LinkedIn
• Click the Me icon at the top-right corner of your LinkedIn homepage
• Select Settings & Privacy from the dropdown
• Select Visibility
• Select Who can see your connections
• Select Only you for the highest security setting.

Anyone can find and contact you on Telegram if they have your username. They will also be able to see your phone number if it is visible to everyone. We encourage you to change your Telegram username to a unique one that you have not used elsewhere (including on social media profiles). Doing so will prevent you from receiving unwanted messages and help you maintain control.

To change your Telegram username, go to Settings > Edit > Username

Two-step verification allows you to set up a password that will be required every time you log into your account from a new device – in addition to the code you get in the SMS. This can prevent your account from being ‘cloned’ or logged into by someone else.

To turn on Two-Step Verification:

• Go to Settings > Privacy and Security > Two-Step Verification > Set Additional Password
• Set your desired password (make sure this is unique and memorable)
• Create an optional hint for your password
• Set a Recovery email (remember to use a safe email!)
• Telegram will send a pin to your recovery email. Enter this pin into the prompt when you receive it.
• Click continue, and you’re done.

Your phone number is an identifying information that is difficult to change, and which gives people access to you. Where possible, you should limit how public your phone number is so that you would minimise the chances of receiving unwanted contact.

Telegram allows you to control who can see your phone number.

• Go to Settings > Privacy and Security > Phone Number
• Set Who can see my phone number to Nobody for the highest security setting
  • This setting gives you the most control over who gets to see your phone number. Under ‘Exceptions’, you can then specify who you want to share your phone number with.
  • If not, you can set Who can see my phone number to My Contacts. People who have already saved your number in their contacts will also see it on Telegram.

Telegram also allows you to control who can find you with your phone number.

• Go to Settings > Privacy and Security > Phone Number
• Set Who can find me by my number to My Contacts for the highest security setting. This means that users who add your number to their contacts will only see it on Telegram if they are already your contact.

Telegram allows you to control who gets to see your Last Seen & Online, as well as your profile photo.

• Go toSettings > Privacy and Security > Last Seen & Online
• Set Who can see my timestampto Nobody for the highest security setting.
• Click Back then click Profile Photo
• Set Who can see my profile photo to My Contacts - this means that only users who you have added as a contact can see your profile photos.

On Telegram, people can forward your messages to others. These forwarded messages can link back to your account. To prevent this, do the following steps:

• Go to Settings > Privacy and Security > Forwarded Messages
• Set Who can add a link to my account when forwarding my messages to Nobody for the highest security setting.

You can control who gets to add you to groups and channels.

• Go to Settings > Privacy and Security > Groups & Channels
• Set Who can add me to My Contacts for the highest security setting. This means that only users who you have added as a contact can add you to groups & channels.

You can control who gets to call you on Telegram. This is useful if your phone number has been compromised.

• Go to Settings > Privacy and Security > Calls
• Set Who can call me to My Contacts

• Log into your Google Account.
• Click on your user photo in the top-right corner of your screen.
• Click Manage your Google Account
• Click Security in the left sidebar
• Click 2-step verification under Signing in to Google
• Follow the on-screen instructions to set up 2-step verification for your Google account.

Use Google’s Privacy Checkup to quickly go through your Google account’s privacy settings. The Privacy Checkup will walk you through setting up auto-delete for location history and your YouTube history. We recommend selecting Auto-delete activity older than 3 months

If you don’t want Google to collect this information in the first place, go to Activity Control and turn off:

• Web & App Activity
