How can I use my existing company, institutional or private email address?

We offer two types of authentication. Mendeley is easy. When you sign up for Mendeley, you can simply use your existing email address.

Google is a bit of a different story. Your @gmail.com is also a Google account, but certainly not the only possible option. When you sign up for a Google account, note that it will pre-fill the username box with @gmail.com. By default, it will create a Gmail account too. However, note the little link below that box "I rather use my existing email address". Click that and Google will allow you to create a Google account using your existing email address.
