Research Gate registration is not complex. Essentially, what you need is a functional institutional email address that you can access. For example, if you are a student or a researcher, you can use the email ID generated by your institution and follow the prompts. If you use an email address that you cannot access, it will be difficult for you because RG often requires verification of the email address you input. I didn’t understand the last part of your question, so I’m unable to provide any suggestions. Cheers
NB: RG is a professional network for researchers, if you do not do research, you may be denied access.@
