Create and activate your account
Understand email confirmation, resend behavior, OAuth signup, and common activation problems.
Why activation is required
Email confirmation proves that you can receive messages at the address attached to the Tnion.SH account. A new account cannot sign in, exchange an OAuth session, use a passkey, or reset a password as a shortcut around this step.
This rule applies to email and password signup as well as new accounts created through Google or GitHub. Provider verification and Tnion.SH activation are separate checks.
Activate a new account
After signup, Tnion.SH sends a time-limited activation link. Open the link in the same browser or another trusted browser. A valid link activates the account, signs you in, and continues to onboarding.
If you did not request the account, do not open the link. You can ignore the message or contact support if the messages continue.
Resend the email
Open the verification page and enter the exact address used during signup. Select Resend email. The response is intentionally the same whether an eligible pending account exists or not.
When a fresh link is issued, older unused activation links are invalidated. Use the most recent message. Check spam, quarantine, and company mail filters before requesting several links.
If the account was already activated, return to sign in. If the account was suspended, the resend action does not reactivate it.
OAuth signup
Google and GitHub sign-in can create an account, but a new OAuth account is redirected to the verification page instead of receiving a session immediately. Open the Tnion.SH email to finish activation.
Returning OAuth users whose Tnion.SH account is already active continue to sign in normally. GitHub sign-in is separate from the GitHub App used to grant a workspace access to private module repositories.
