Turning on two-factor login signed everyone out
Why all your staff were signed out after you turned on two-factor login, and how to get everyone back in.
everyone logged out, all staff signed out, logged out suddenly, two factor, 2FA, authenticator, can't log in, lost phone, lost backup codes, set up two-factor authentication screen, code not working, invalid verification code, expired two-factor tokenNeeds the Standard plan or higher. See plans
What you see: right after someone turned on Require two-step login for staff, every staff member was signed out on every computer and phone. When they sign in again, BytePhase asks them to set up an authenticator app.
This is expected. Turning the setting on signs out all staff at once, so everyone signs in again with the extra step.
Try these fixes
Section titled “Try these fixes”1. Sign in and set up the authenticator
Section titled “1. Sign in and set up the authenticator”Each staff member does this once.
- Install an authenticator app on your phone, for example Google Authenticator, Microsoft Authenticator or Authy.
- Sign in with your email and password.
- On Set up two-factor authentication, scan the QR code with the app. Or type the key shown under Or enter this key manually.
- Type the 6-digit code from the app.
- Save the backup codes, then tap I’ve saved my codes.
See Turn on two-factor login for your staff.
2. The code isn’t accepted
Section titled “2. The code isn’t accepted”- Type the newest code. Each code changes every 30 seconds.
- Check that the phone’s date and time are set to automatic. A clock that’s off makes the codes wrong.
- If you waited a few minutes after typing your password, tap Back to login and sign in again.
3. Lost phone or new phone
Section titled “3. Lost phone or new phone”- On the code screen, tap Use a backup code.
- Type one of the backup codes you saved. Each code works once.
- Once you’re in, open your profile menu, choose Two-factor login, then Disable 2FA. At your next sign-in you can set up the new phone.
4. No phone and no backup codes
Section titled “4. No phone and no backup codes”A staff member can’t get in without one or the other.
- The shop owner can turn off Require two-step login for staff for a while. Staff then sign in with just their password.
- Once the person is in, turn the setting back on. Note: turning it on signs everyone out again.
Still not working?
Section titled “Still not working?”Contact support and send:
- your shop’s web address and the staff member’s email
- whether they see the set-up screen or the code screen
- the exact message on screen
