How to use User-Agent: instructions for customers
User-Agent is a string, a browser identifier, which is passed to the server when you access a website page. The identifier contains information about the type of browser, the type of system on which the browser is running, and the browser version. Example User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36
User-Agent is used by social networks when composing a device or browser fingerprint, so various browsers with device fingerprint changing functionality will substitute this value for each new tab.
If the account you purchased comes with User-Agent, you should use it to reduce the likelihood of account lockout.
The setup procedure may vary depending on the software you plan to use, but generally the User-Agent value is simply copied into the settings field of a program with a similar name.
You can get examples of User-Agent for different browser versions and systems by using the chrome browser add-on, User-Agent Switcher and Manager.
Attention, changing User-Agent value is only a part of account security, it cannot be considered as a full-fledged device fingerprint change, which should be applied to each account separately.
