You sign in at the SunAuth portal in two steps: first your username, then your password. After a successful login you reach the landing portal where you choose the app, group and property.

The SunAuth portal is the only sign-in page of every SunTatva app (SunPMS, SunPOS, SunParking, SunSpa, SunHardware). No app has a login page of its own: opening an app, logging out of it or an expired session always brings you back here. SunPOS staff sign in here with their own SunAuth account too; the PIN set on the SunPOS Users screen is only the approver PIN for discounts and voids.

Watch: Logging in

Before you start

  • You have an account and a verified e-mail.
  • Staff users: your owner or administrator gave you the username and a password.

Screen layout

The page has a dark brand panel on the left ("One login for all your apps.", the five apps listed, a green "All systems operational" status) and the white sign-in card on the right. The card starts with a two-segment progress bar labelled Identification (step 1) or Authentication (step 2) and a small overline "Step 1 of 2" / "Step 2 of 2". On tablets and phones the brand panel shrinks to a bar on top. The footer under the card shows the copyright and the portal version.

Step 1 of 2: Identification (title "Sign in to SunTatva Apps")

Field / button What it means Rules
Username Your login name (the @ icon is only decoration). Required ("Please enter User Name."). Press Enter or click Continue.
Continue Moves to the password step. The username is not checked yet.
Create account Link at the bottom left of the card. Opens Sign up.
Terms of Service (sentence under the buttons: "By continuing, you agree to the Terms of Service of .") Opens the current agreement for reading.

Step 2 of 2: Authentication (title "Welcome, ")

Field / button What it means Rules
Not you? Link under the title "Welcome, " (with a person icon). Goes back to step 1 so you can type another username.
Password Your password. The eye icon shows or hides it. Required ("Please enter Password.").
Security check (picture with a sum, Type the answer, round arrow for a new picture) Appears after two failed sign-ins for this username or from your network (within 15 minutes). The server decides; it replaces the old "I'm not a robot" tick box. Must be solved ("Please solve the security check."). Each picture works once; after a failed sign-in answer the new picture.
Forgot password? Starts password recovery for the typed username.
Sign In Checks the password. Press Enter works too.
Terms of Service link Opens the current agreement in a window titled " — Agreement & Privacy Policy". Click OK to close.

How to log in

  1. Open the portal. Type your Username and click Continue.
  2. Check the name in "Welcome,..." is yours. If not, click Not you?.
  3. Type your Password and click Sign In.
  4. If this is your first login after a new agreement, the owner must accept the terms (see Terms and conditions). Result: the landing portal opens (Landing portal).

If you press Sign In with the password empty, the message "Please enter Password." opens:

What happens behind the scenes

  • Your username and password travel in the body of a secure (HTTPS) request, never in the address; the server checks them and keeps only a hash of the password.
  • After 5 wrong passwords (the default, set by SunTatva) the account is locked. Owners must contact SunTatva support; staff must contact their hotel administrator. Only sign-in attempts count: a wrong password in a confirmation inside SunPMS (Confirm with Your Password, Verify Password) never counts and cannot lock the account.
  • The Security check appears after 2 failed sign-ins. The server counts failures per username and per network address for 15 minutes, so refreshing the page does not remove it. The answer is verified on the server.
  • Too many sign-in attempts in a minute are refused with "Too many requests. Please wait a little and try again." Wait and retry.
  • If an action is not allowed for your account, the screen shows the reason from the server (for example "You are not allowed to view / change this account.") instead of failing silently.
  • If the e-mail is not verified, the verification step opens instead (Verify e-mail).
  • If the password is older than three months you are asked to set a new one (Password expired).
  • SunTatva staff (SunAdmin accounts) are sent straight to the admin console.
  • Opening the portal with ?logout=1 in the address signs out and clears the saved session.
  • If you are still signed in and open the login page again, you are taken to the landing portal automatically (after the terms have been accepted).

Tips and FAQ

  • Q: Is the username case sensitive? A: Type it exactly as created; use the same case you registered with if a login fails.
  • Q: I locked myself out. A: Wait for support to unlock it. Resetting the password by e-mail does not remove a lock by itself; contact support.
  • Q: The page shows "Version 1.0.1" at the bottom. A: That is the portal version; quote it when contacting support.
