As part of some increased security features you may have already noticed being added to Deploy, we've now deployed the option to restrict access to your account to specific IP addresses or ranges.
To enable this feature, simply head to your Settings tab, then choose Yes - only allow access to the IP addresses specified under IP restriction, then enter any IP addresses or ranges you wish to allow access to, clicking Save Changes to finish.
As the page states when setting this up, you'll need to ensure you add your current IP so that you're not accidentally locked out of your account.
If you have any questions, please don't hesitate to get in touch.
