Some Tomba apps sign you in with a code instead of your password. The app shows a code of 8 letters, and you approve it on the Tomba website at app.tomba.io/device. You never type your Tomba password into the app.
Which apps use a sign-in code
These Tomba apps show a sign-in code:
The Tomba browser extension
The Google Sheets add-on
The Excel add-in
The Tomba CLI, a tool for developers who work in a terminal
Approve a sign-in code
Step 1. In the app, click Sign in with Tomba. In the Tomba CLI, type tomba login instead. The app shows a code such as BCDF-GHJK. Some apps also open the Tomba page for you, or give you a button that opens it.
Step 2. If no page opened, go to app.tomba.io/device. Sign in to Tomba if you're asked to.
Step 3. On the Sign in to Tomba page, type the code and click Continue. If the page opened with the code already filled in, Tomba checks it for you.
Step 4. The next page names the app, followed by "would like to access your Tomba account". Below "They will be able to perform the following actions:", check what the app asks for. Then click Authorize.
Step 5. When you see Device Authorized, close the tab and go back to the app. It signs in by itself.
About the sign-in code
A sign-in code has 8 letters, shown in two groups of four, such as
BCDF-GHJK.You can type it with or without the dash, in capital or small letters.
A code lasts 15 minutes, and you can use it only once.
⚠️ Important: Only approve a code that you see in your own app, right after you started the sign-in. If someone sends you a code, don't enter it.
Messages on the sign-in code page
"Please enter the code displayed on your device": the box is empty. Type the code that the app shows.
"Code must be 8 characters": type all 8 letters of the code.
"Invalid code format": the code has a typo, such as a number. Codes have letters only.
"Invalid or expired code": the code is wrong, more than 15 minutes old, or already used. Start the sign-in again in the app to get a new code.
"Access denied. You can close this tab.": you clicked Cancel, so the app isn't signed in. To sign in after all, start again in the app.
"An error occurred": the approval didn't go through. Start the sign-in again in the app.
Common questions
What if the code expired?
Go back to the app and start the sign-in again. The app shows a new code. Then approve the new code on app.tomba.io/device within 15 minutes.
Do I need to sign in to Tomba first?
Yes. If you aren't signed in, the code page sends you to the sign-in page first, then brings you back.
