Linked accounts

Link a Google or GitHub account so you can sign in with it, see what linking does, and unlink an account.

On this page

A linked account lets you sign in with an account you already have at another provider, such as Google or GitHub, instead of typing a password. The Linked accounts tab says Sign in with an account you already have at another provider.

Which providers you can link depends on your organization, so the list on your account may be shorter, or empty. When the platform offers none, the tab says Linked accounts are not turned on and This platform does not offer signing in with another provider. On the Security overview, the Linked accounts row only appears when linking or merging is offered.

What linking does#

Linking connects the provider's account to your TDACorp account. After that, the sign-in page can offer a button for that provider, and choosing it signs you in to your own account. The platform needs the provider to share an email address for the account.

Signing in this way counts as a single step. Changing your security settings still needs a second factor used in the last 30 minutes. If you only have a linked account, the confirmation dialog can offer Continue with the provider, which sends you back to sign in at the provider again. See The Security overview.

The Linked accounts tab of the security settings: the page says No accounts linked. — Linked accounts: none linked yet. Sample data./account/security/linked

Link an account#

When nothing is linked yet the tab says No accounts linked. Under Available to link each provider has a button.

Open Security, then the Linked accounts tab.
Under Available to link, select Connect followed by the provider's name, for example Connect GitHub.
The button reads Taking you to the provider while you leave the page. The page says You leave this page to sign in with the provider, then come back to the Security overview.
Sign in at the provider and approve if asked.
You return to the Security overview with a message. Account linked. means it worked.

The Linked accounts list then shows the provider with a Linked badge, the email address the provider holds, when you linked it, and when you last used it to sign in.

When an organization you belong to has a single sign-on connection that can be linked to your account, the tab shows a second section, Link your organization sign-in. Each row names the connection and the organization. Select Link sign-in on it; the page says You leave this page to sign in with your organization, then come back to the Security overview. It must use an email address already verified on this account. You sign in at your organization's identity provider and return to the Security overview. The link is refused unless you are a member of that organization, so a connection of an organization you do not belong to never appears or works. Linking it is what lifts a Blocked membership when your organization requires single sign-on; see Single sign-on and managed accounts.

If linking fails#

The overview shows one of these messages.

Message	What it means
The account could not be linked: it was started from a different session.	The link was begun in another browser or session. Start again from this one.
The account could not be linked: the provider shared no email address.	The provider did not share an email address with the platform. Use another account, or one that shares an address.
The account could not be linked: it could not be used to sign in.	The provider's account could not be used to sign in.
That account is already linked to another sign-in here.	That provider account is already attached to a different TDACorp account. Unlink it there first, or use another.
That provider is not available right now.	The provider is not offered at the moment. Try again later.
The provider sign-in did not finish.	You left the provider page without finishing. Try again.

If you are a member of an organization that has set up its own company sign-in, and you have not linked it yet, the tab shows a further section titled Link your organization sign-in. Each row names the connection and the organization. Select Link sign-in on the row. The page reads Taking you to the provider and says You leave this page to sign in with your organization, then come back to the Security overview. It must use an email address already verified on this account.

Like linking a provider, this needs a second factor used in the last 30 minutes.

Unlink an account#

On Linked accounts, select Unlink on the row of the account.
The dialog is titled Unlink followed by the provider's name and a question mark. It says you can no longer sign in with it, that other signed-in devices are signed out, and that if it is your only way to sign in, the platform will not unlink it.
Confirm with Unlink. The page says Account unlinked.

Unlinking does not delete anything at the provider. Under the list the page reminds you of that. If the linked account is your only way to sign in, the platform refuses with That is your only way to sign in, so it cannot be removed. Add another first. Add a passkey or set a password first.

Two accounts of your own#

If you have a second TDACorp account of your own, the tab can offer Merge another account into this one, described under Have a second account of your own? See Merge accounts. It shows only where merging is available.

Managed accounts#

An account that an organization manages (a managed identity) cannot add, change or remove its own sign-in methods here: those requests are refused, because the organization's directory connection is its only way in.
