Guaranteeing protection against recovery is quite a difficult task.
To help you avoid this problem, we have made several recommendations.
It is significantly safer to buy a Roblox account with an email address linked to it. The most secure account should always have:
The original email address and the first confirmation email about registration of this account or the first email about linking the email address to the account (do not confuse these emails when changing your email address). If the email is original, the risk of account recovery by the previous owner is significantly reduced.
In the Roblox account settings, you need to check the email address, phone number, and Google Authenticator associated with the account. You should have full access to all of these.
If you're buying an account with an email, make sure the seller gives you full access to this email. Then change all passwords and enable two-factor authentication.
Before buying an account with an email, you can ask the seller to send you a message from the email address you're purchasing. In this email, the buyer can write an agreement regarding the sale of the email together with the Roblox account and attach screenshots of your transaction from Rb2play.com.
