Login SSO · Family Sites
TFlow doesn't stop at the main app. Store, Guild, and Studio are family sites that each open at their own address, but you only need to log in once. Once you're logged in on the main app, you won't be asked to log in again no matter which service you move to.
💡 Who is this for? Anyone who wants to use product promotion (Studio), a public storefront (Store), and a trade community (Guild) together. If you're wondering "Do I have to sign up again?" or "Why was I logged out?", read this page. The answer is almost always "One account covers everything."
1. One Login for Every Service (SSO)
If you were told you need to sign in, or that your session expired — click Log in at the top right. After logging in you are returned to the screen you were on. TFlow, Store, Guild, and Studio share one account, so there is no separate sign-up.
Every site that ends in .tflowx.com shares a single login session.
- Once you log in on the main app, you don't need to log in again when you move to Store, Guild, or Studio.
- The family sites have no separate sign-up. You use them all with your TFlow main app account.
ℹ️ Even without logging in, you can view each site's public areas (browsing the storefront, reading community posts, the Studio intro, and so on). Logging in is required for actions like posting, requesting quotes, or generating content, and when you log in at that point you're automatically returned to the screen you were on.

2. How to Reach the Family Sites
Family sites open in a new tab.
| Entry point | Location |
|---|---|
| Family Sites at the bottom of the sidebar | The Store / Guild / Studio links in the Family Sites section at the very bottom of the main app's left sidebar |
| Landing page footer | The Family column in the footer at the bottom of the landing (intro) page |
ℹ️ Services that aren't connected yet are automatically hidden from the list. If a particular service link is missing, that service simply isn't open yet.

💡 Troubleshooting (FAQ)
If you can't log in, or forgot your password
What to do depends on the message on screen.
| What you see on screen | What to do |
|---|---|
| "Invalid email or password." | Check your email and password again. If you can't recall it, reset it with Forgot your password? on the login screen. |
| "This email is not registered." | You may have signed up with a different address. Try the email you use at work. |
| "The reset security code has expired or already been used." | Press Send Security Code to get a new code and enter it. |
| "The security code has been invalidated after 3 incorrect attempts." | Request a new code on the same screen. |
| "Your account has been locked due to too many password reset requests." | Ask your company Master or TFlow customer support to unlock it. |
Password reset steps — Forgot your password? on the login screen → enter your email and press Send Security Code → enter the code from the email → enter a new password twice (8 or more characters mixing letters, numbers, and symbols) → Change Password.
Other questions
Q. How do I sign up for Store/Guild/Studio? A. There's no separate sign-up. Log in with your main app account and SSO gives you access to every service. (Guild has a first-time onboarding step where you only pick a nickname.)
Q. I'm logged in on the main app, but I'm logged out on a family site. A. If your browser is set to aggressively block cookies, the shared login state may be blocked. Just click Log in once on that site and your session will persist afterward. If it keeps happening, check your browser's cookie-blocking settings.
Q. A particular family site link is missing from the sidebar. A. Services that aren't open yet are automatically hidden from the list. Ask your company Master.
Q. The family site won't open in the same tab. A. That's expected. Family site links open in a new tab so your workflow isn't interrupted.
