Once you have created your test user, you can then visit the link that was generated and set up a password. Once you have set up your test viewers password, you can then log in as that viewer and go through the same journey your viewers (clients) will.
If you're currently logged into the admin, you can:
Click logout in the bottom left-hand corner
Once on the login screen, you can enter your test viewers credentials.
Take the same journey your viewers (clients) will experience.
Test viewers will not count toward your viewer journey credits.
If you wish to remain logged into the admin, then you can always open a new "incognito" window and visit www.moneyalive.io and log in as your test viewer.
