What are backup codes and how do I use them?

Backup codes are 8 spare codes you get when you turn on two-step sign-in. Each one signs you in once, instead of the 6-digit code from your phone. Use them when your phone is lost, broken or simply not with you.

Where to find it

Admin › Administration › Security › Two-step sign-in (প্রশাসন › নিরাপত্তা › দুই-ধাপের লগইন). The page shows how many backup codes you have left, next to the date two-step sign-in was turned on.

How it works

The codes appear once, right after you turn on two-step sign-in, in a box titled "Your backup codes — save them now". They look like 4F7K-9Q2M.
They are kept hidden in the panel. Nobody, not even the owner, can see them again.
On the sign-in code page, type a backup code in the same box as the 6-digit code and press Sign in. Capital or small letters both work, and the dash is optional.
Each code works only once. After use it is gone, and the page shows one fewer left.
A backup code can also turn two-step sign-in off on the Two-step sign-in page, when it is not a must for your job.

Step by step: make new codes

Open Two-step sign-in.
Type the current code from your authenticator app in Code from the app.
Press New backup codes (নতুন ব্যাকআপ কোড).
Save the 8 new codes. Every old code stops working at once.

Good to know

Keep them away from your phone. Write them on paper or keep a photo somewhere other than the phone that has the app.
Running low? Make new codes before you use the last one.
New codes need the app. You cannot make new backup codes with a backup code. If your phone is gone, sign in with a backup code, then ask the store owner to turn two-step off for you, or turn it off yourself (when allowed) and set it up again.
Making new backup codes also ends every "trusted" device, so each one asks for a code once more.

Common problems

"That code is not right." The backup code was already used, or a letter was mistyped. Try another one.
No codes left and no phone. A staff member asks the store owner to turn two-step sign-in off for them. The owner should keep their own backup codes extra safe: the Turn off (lost phone) button works on other people, never on yourself.
