To unblock friends on Roblox, start by logging into your Roblox account. If you’re on a computer, sign in at www.roblox.com using any web browser. On the Roblox app, tap the three dots (•••) and select Settings.
Next, access your account settings. On the Roblox app, tap Settings. You’ll find this option underneath Security on the settings page.
Then, navigate to the privacy settings. On the app, tap Settings again, and select Privacy from the left sidebar.
Now, show the blocked users list. Scroll down and click Show under Blocked Users. You will see all the people you have blocked on Roblox.
Finally, unblock the user. Click Unblock next to the user you want to unblock. If prompted, click Save to apply your changes. If you have an account PIN enabled, you might need to disable it temporarily by going to Settings > Parental Control and toggling off the Parent PIN. You may need your parents’ help if they set the PIN.
