Online security is very important, especially if you´re buying and holding cryptocurrency. One way to secure your accounts is using your phone number as 2-factor authentication (also known as 2FA). Although not the safest option, it is certainly better than having no extra level of security. As you will be relying on your phone number as security, it’s important to keep your information up to date.

So what if you have a new phone number or had your existing phone lost or stolen? Well, with the Binance exchange, there will be 2 ways to change your phone number, depending on if you still have access to your phone.

Binance 2FA Security Key

It’s important to protect your crypto assets, especially on cryptocurrency exchanges such as Binance. Using your mobile phone as two-factor authentication is certainly better than no security, however I would recommend increasing your security.

Binance recommends using a security key. One that I personally use and is compatible with Binance is the Yubico YubiKeys. The YubiKey you choose will depend on the hardware you use, I have an older MacBook Air which I use the YubiKey 5 NFC, and a YubiKey 5Ci for my newer MacBook Pro. The YubiKey 5Ci is also compatible with my iPhone 12.

So, just make sure you do your research before choosing a security key, it does take time to get used to it, but it’s a great bit of kit.
