LINE Registration and Login
Register or log in to DodoAI using your LINE identity; no email required, suitable for LIFF and LINE users.
What this guide covers
This explains how to register or log in to DodoAI using LINE, as well as the data relationship with LIFF and LINE text after logging in.
← Overview of Registration and Login
Who is it for?
- Users who primarily use LINE
- Users who do not want to fill in their email on the login page
- Users who want to log in with one tap when opening LIFF in LINE
LINE login does not require an email; an email can be optionally added in Profile after logging in.
Entry points
| Scene | Action |
|---|---|
| Browser / App | Open Login or Register |
| LIFF in LINE | Redirects to the same login page when not logged in, click LINE |
Login steps
- Open the Login page.
- In the top "Sign in with Google or LINE" section, click LINE.
- You will be redirected to the LINE authorization page to confirm that you allow DodoAI to use your LINE identity to log in.
- After successful authorization, you will automatically return to DodoAI and will be logged in.
The first time you log in with this LINE identity, the system will automatically complete registration, and you won't need to fill in your email.
Registration steps
- Open the Register page.
- Click LINE under "Sign up with Google or LINE".
- Once LINE authorization is complete, registration and login both finish automatically.
The registration page does not require an email or password.
Using in LIFF
- Open the DodoAI LIFF link or menu in the LINE chat.
- If not logged in, you will be directed to the login page; selecting LINE is usually the easiest (since you are already in the LINE client).
- After a successful login, return to LIFF to use the Space, YOYO and other tabs (see the capabilities subset in Channel Comparison).
Differences with Google
| LINE | ||
|---|---|---|
| Location | Same OAuth area on login/register page | Same |
| Need to fill in email? | No | No |
| Suitable scenarios | LINE users, LIFF | Users with existing Google accounts |
The operation paths are the same, with only the authorization platforms being different.
LINE text and App data
- LINE sign-in addresses the App / LIFF account identity.
- To use text for tasks and more in the LINE chat window, it must be linked with the App account to view everything in Space.
- For more details, see LINE and Account Linking and LINE and App Data Relationship.
What you can do after logging in
- View your LINE User ID in Profile (if linked).
- Optional: add your email (not mandatory).
- When logged in with the same account as in the browser, data syncs to the cloud → Login through different channels.
