Your Nexl account is directly linked to your email account—it's how we can automatically create Contacts when you email someone new, and show you each Contact's firm-wide email interactions in their Activity Feed.
Because your Nexl account is created from your email account, it's not possible to change your account details within Nexl—all of that information is sent into Nexl from your email provider. And since each user only has one work email address, it's also not possible to log out.
