Your Paxful wallet is just as secure as your password (so make sure that your password is a good one).
Not only are our servers very well guarded to the highest banking specifications, but as an additional layer of security, 2-factor extra protection can be enabled whenever you log into your account and when you send out bitcoins as a buyer or seller. We also support Google Authenticator, Authy, and SMS based 2-factors.
As long as we’re talking about security, beware of any phishing sites. ALWAYS make sure you are on https://paxful.com/ before you enter any account details. Never give your account details to anybody. Paxful support will NEVER ask for your account password or one-time password. Note that Paxful has no Skype or Phone support. It is impossible for Paxful to take all the phishing websites down, so you, as a user, should learn how to protect yourself from any sort of scam.
