I have reset the security token thrice. And I waited for 1 hour , to receive the email from salesforce. I have still not received the security token from Sales force.My org is Sandbox.
Here are 2 things you should check:
- Check to make sure that your email address is correct in your advanced user settings.
2.Check under Administer>Email Administration>Deliverability and make sure the Access Level allow emails to be sent out. Admins sometimes set this to "No Access" to prevent users from receiving emails from a test environment.
When you create a sandbox, users email addresses are modified to prevent users receiving multiple alerts during testing. You need to change your email address back to a real one for any emails to actually be delivered.
