### 2FA

STEPN has integrated Google 2 Factor Authentication to safe guard users' transaction and change users' information. Please save your 2FA code at place that is safe. Resetting 2FA could take month.

**Note: Users should never give away their Verification Codes nor 2FA Code to anyone, not even to the STEPN team, as we don't need it/use these codes. Only scammers ask for these codes.**

### **Security**

Aside from allowing players to log in with a password, user can also use a one-time Verification Code system sending to their email address to log in.<br>
