Where to save two-factor backup codes

Turning on two-step sign-in usually ends with a list of codes and the words “store these somewhere safe.” Here’s what that can mean in practice.

Updated October 2026.

What you’re being given

Either one can get someone into your account, so treat it like a password. And you’ll need it on the day you’ve lost the device that normally signs you in, so don’t keep the only copy on that device.

Good places, and what to avoid

Whatever you choose, write down which account the codes belong to and the date you made them. Old codes stop working when you make a new set.

How Slinky does it

Slinky has a place called Recovery, just for these:

Questions

Should backup codes go in the same place as the password?

It’s a trade-off. Keeping them apart means one leak doesn’t give away both. Keeping them together means one lost vault loses both. Many people keep the password in Apple Passwords and the codes somewhere else, plus a printed copy of the most important ones.

What happens when I use a backup code?

Each code usually works once. Slinky crosses a code off when you copy it, and warns you when only a few are left so you can make a new set on the website.

Does Slinky store crypto wallet recovery phrases?

No. If you paste something that looks like a wallet recovery phrase, Slinky says so and doesn’t save it. Those belong on paper or a hardware wallet.
