Signing in to Arca with Salesforce
If your team uses Salesforce as your sign-in provider, you'll log in to Arca by clicking a Salesforce button instead of entering an email and password. This guide explains how it works, what to do when it fails, and how the account behaves differently from a regular one.
How Salesforce sign-in works
When Salesforce sign-in is set up for your account:
- Open the Arca sign-in page and choose your account.
- Click Log in with Salesforce.
- You're redirected to Salesforce to authenticate (if you're already signed in there, this is instant).
- Salesforce sends you back to Arca and you're signed in.
If you don't see the Log in with Salesforce button on the sign-in page, Salesforce sign-in hasn't been enabled for that account yet — see the setup section below.
How a Salesforce account behaves differently
- Your password is managed in Salesforce. Don't use Forgot Password in Arca on a Salesforce account — reset it in Salesforce instead.
- Your profile is managed in Salesforce. Changes to your name, email, or photo flow from Salesforce; editing them in Arca isn't supported for SSO users.
- Signing out: end your Salesforce session to fully sign out.
Setting it up for your team
Salesforce sign-in is configured per Arca account by the Arca team — it isn't self-service. To enable it, contact Arca support with:
- The Arca account you want to enable it on
- Your Salesforce login domain (e.g.
https://yourcompany.my.salesforce.com) - A Salesforce Connected App in your org configured with Arca's callback URL (Arca support will provide the URL)
Common problems
The "Log in with Salesforce" button isn't on my login page
-
Cause
Salesforce sign-in hasn't been enabled for that Arca account yet.
SolutionContact Arca support to set it up (see above). The button appears only on accounts where Salesforce is enabled.
Sign-in fails or the popup closes with an error
-
Cause
- Confirm the Salesforce user is active and has an email on file.
- Have your Salesforce admin check the Connected App's redirect URI matches what Arca expects.
- Note the exact error text shown and send it to Arca support — it usually comes straight from Salesforce.
Most often this is a Salesforce-side configuration issue — a mismatched redirect URI, expired Connected App credentials, an inactive Salesforce user, or a Salesforce account without an email.
SolutionI tried Forgot Password in Arca and the link doesn't help
-
Cause
Your password is managed by Salesforce, so resetting it in Arca won't take effect.
SolutionReset your password in Salesforce, then sign in again with the Salesforce button.
"Updating a user with SSO is not allowed"
-
Cause
An admin tried to edit a Salesforce-managed user in Arca's user form.
SolutionUpdate the user's details in Salesforce; Arca will pick up the change on next sign-in. For role/permission changes inside Arca, see Managing team members.
Still having trouble?
Contact Arca support and include:
