Two-Factor Authentication is an extra layer of security used to help prevent unwanted or illegal access to your Stake account. Where traditionally you can login to an account with simply a username and a password, this extra level of protection lets you add an additional security step to your login process by requesting a randomised code from a linked mobile device you own.
When you have setup 2FA on your account, this also extends the additional security step to withdrawals, tips and everything regarding you sending funds.
To start this process, you’ll need to install either Authy (recommended) or Google Authenticator on your chosen device. You can then head over to your Settings > Security page to link your device with your Stake account by either copying the string provided into the 2FA app or simply using the QR Code shown. From there, you will be required to enter the code generated on the app into the form on your security settings page.
Afterwards, you will be sent an email in which there will be a link that will finally enable 2FA on your account. This is an extra security precaution that prevents unwanted access.
It is very important that you DON'T share your QR Code or the string provided with anyone else, or they may be able to get access to your account.
