If you didn’t activate your 2FA with Google Authenticator, you will see a small padlock on the top right area of your wallet, as shown in the picture below.
Once you login to your wallet for the first time, the padlock is closed. This means that your wallet can perform exchanges and check balances and your history, but you are not yet able to execute outgoing transactions.
To unlock your withdrawal, click on the padlock or visit this link. Then you will receive an email to confirm the procedure. Click on the link you see in the email to remove the lock.
The unlock will last for 7 days and you can decide to open or close the padlock by yourself. If you change your internet connection, the padlock will be automatically closed.
To do so, you just need to click on the open/closed padlock to open or close it.
The padlock is active only if you don’t have the OTP with 2FA key activated.
If you want to activate your OTP, please read this guide.
