Every sign-in screen carries a line under its title. Leave it blank and your clients read ours. Write your own and they read yours instead, from the moment they sign in for the first time.
What you need: the Whitelabel plan, since the sign-in screen only carries your identity there at all.
Where it lives
Open Branding and find Login screen welcome copy on the Identity card, alongside your app name, logo and brand color. It takes up to 200 characters, and the hint under the field counts down as you type.

The change saves itself, the same as the rest of the card. Anyone signing in from that point on sees the new line. A session already open keeps the old one until it reloads.
What to put there
1 line of reassurance or instruction beats a paragraph. Say what the location is for, who the reader works with, or what to do first: "Sign in to review this week's reviews" tells a client's team exactly what waits for them. Keep marketing language out of it. Nobody reads a sales pitch on the way to signing into a tool they already pay for, and the box is too short for one anyway.
Where it shows, and where it does not
The message prints on the sign-in screen alone, under your name and logo. It never reaches the signup or password-reset screens, and it never reaches anyone signing into ReviewComet itself: our own hosts always show our own line, whatever you write here.
It also stays off any of your own hosts until your custom domain finishes verifying. Until then, a client who tries to sign in lands on our address instead of yours, sees our name, and reads our line, not yours.

Why this is worth writing
A client's team signs into the same screen every day. Leave it blank and the screen still works. It says nothing back.
