The token is an automatically-generated key that must be added to the end of your Salesforce password in order to log in to Salesforce from an untrusted network.
For example, if your password is 'mypassword' and your security token is 'XXXXXXXXXX', then you must enter 'mypasswordXXXXXXXXXX' to log in. Security tokens are required when you log in via the Act-On connector.
To reset your security token:
- Click Your Name (in Salesforce) in the upper right-hand corner.
- Click My Settings > Personal > Reset My Security Token.
- Click the Reset Security Token button.
- The new security token will be sent via email to the address on your Salesforce user record.
