Signing In

How to sign in to your Mercayo admin, set or reset your password with a 6-digit code, and what happens with two-step sign-in.

Last updated 19 October 2026

You sign in to the Mercayo admin with your account's email and password. If your account uses two-step sign-in, you also enter a 6-digit code from your authenticator app. This article covers signing in, setting a password if you never had one, and resetting a forgotten one.

Sign In

  1. Open the admin's sign-in page: Sign In to Your Store.
  2. Type your Email and Password ("Use the email and password of your Mercayo account.").
  3. Press Sign in.

What happens next:

  • With one store, you go straight into it, on its Home.
  • With several stores, you see Choose a Store, with each store you are on, and pick one. See Switching Between Stores.
  • With two-step sign-in on, you are asked for the code from your authenticator app first. See Two-Step Sign-In.

If the email or password is wrong, the page says so and nothing else happens. To keep password guessing slow, an account allows 10 tries in 15 minutes (and one address 20); after that the page asks you to wait and try again.

You Signed Up with a Code and Have No Password

Creating a store confirms your email or mobile number with a 6-digit code; it does not ask for a password. To sign in with a password later:

  • You signed up with an email: use Forgot password? on the sign-in page to set a password (below). The admin's Change Password page says the same: "Signed up with a code and never set a password? Sign out and use Forgot password to set one."
  • You signed up with a mobile number: the sign-in page works with email and password. Open the sign-up page and confirm your mobile number again with the code: that signs you in, and the admin's main address then shows your stores. If you would like to sign in with an email and password instead, write to Mercayo's support.

Forgot Your Password

  1. On the sign-in page, press Forgot password?: Reset Your Password.
  2. Type the Email you sign in with and press SEND CODE. "If an account uses that email, a code is on its way. It can take a minute; check your spam folder too."
  3. Type the 6-Digit Code, then your New Password twice (Type It Again). At least 8 characters.
  4. Press SET NEW PASSWORD. You are signed in.

How Long You Stay Signed In

You stay signed in on that browser until you sign out (account menu, Sign out) or your session ends. Signing out on one device does not sign you out elsewhere. On a shared computer, always sign out.

Questions

Why do I never get the code email?

Check the spelling of the address and your spam folder, and wait a minute. Then press SEND A NEW CODE. See Can't Sign In.

What if I lost the phone with my authenticator app?

Use one of your recovery codes on the code step (Use a recovery code instead). Without them, contact Mercayo's support, who can reset two-step sign-in for your account.

Can my staff share my sign-in?

No, and they do not need to. Invite each person with their own account and the role they need. See Staff and Roles.
