Sign-In and Security Settings

Who on your team must use two-step sign-in, how many days new members have to set it up, and how long staff invitation links work.

Last updated 19 October 2026In your admin: Settings › Sign-In and Security

"Who must use two-step sign-in, and how long staff invitations work." Settings › Sign-In and Security protects your store's admin. Two-step sign-in means a code from an authenticator app at every sign-in, so a stolen password alone cannot open your store.

How This Page Works

Settings pages share one way of working (see Settings Home):

  • Each card groups the settings of one feature, with a line saying what it is for. Its main switch turns the whole feature on or off.
  • Change what you need; a save bar appears with SAVE. "Settings saved." Nothing changes on your store until you save.
  • USE DEFAULT puts a setting you changed back to Mercayo's default.
  • A setting Set by Mercayo for your store shows Locked (with Mercayo's reason when given) and cannot be changed here; "Mercayo allows … for your store." shows a range Mercayo has set.
  • If a teammate saved the page after you opened it: "Someone else saved these settings after you opened the page, so yours were not saved. Reload to see theirs."
  • Anyone who can see settings can look ("You can see these settings. Changing them needs the settings right."); saving needs the right to change settings.

Questions

A staff member lost their phone. What now?

They use a recovery code on the sign-in code step. Without one, they contact Mercayo's support, who check who they are before resetting it.

Does two-step sign-in apply to shoppers?

No. These settings are for your team. Shoppers sign in with a code or Google; see Shopper Accounts Settings.
