Lost 2 factor authentication app

Lost 2 factor authentication app


Lost or replaced the phone with your authenticator app on it? You can still get back into your SimplyPrint account. This guide shows the ways in, from quickest to slowest, and how to set two-factor up again on your new phone.


Table of contents


1. Use a passkey or security key

If you've added a passkey, click Sign in with a passkey on the login page. A passkey signs you in without the two-factor step. See Sign in to SimplyPrint with a passkey.


If you've added a security key, such as a YubiKey, sign in with your email and password and touch the key when you're asked. See Use a security key (YubiKey) for two-factor authentication.


Then set up your new phone, as described below.


2. Use a recovery code

When you set up two-factor, SimplyPrint gave you a set of recovery codes to download or copy. Each one gets you in once.


  1. Go to the SimplyPrint login page at simplyprint.io/panel/login, and sign in with your email and password.
  2. When you're asked for your code, click Use a recovery code instead. If the link says Try another way, click it, then Enter one of your recovery codes.
  3. Type one of your codes. Spaces and dashes don't matter. Older, longer codes (two blocks of 10 characters) must be typed with the same capital letters.
  4. Once you're in, click Open security settings and set up your new phone, as described below.


SimplyPrint emails you every time a recovery code is used. See Two-factor recovery codes: use them and get new ones.


Set up two-factor on your new phone

  1. Open the Security & password tab in your account settings (simplyprint.io/panel/user_settings/security).
  2. If you have security keys, the authenticator app can't be removed while any key is left. If you still have a key, first click Get new codes on the Recovery codes row, confirm with your key and save the new codes. Then remove every key: open the menu next to each one in the Security keys list and choose Remove. You can add your keys back afterwards.
  3. On the Authenticator app row, click Remove. Confirm it's you with a passkey or a recovery code. Each code works only once, so don't reuse the one you signed in with.
  4. Click Set up on the Authenticator app row, scan the QR code with the authenticator app on your new phone, enter the 6-digit code and click Turn on.
  5. Save your new recovery codes. Your old ones stopped working when you removed the app.


For the full setup steps, see How to enable 2 factor authentication.


Many authenticator apps, such as 1Password, Authy, Google Authenticator and Microsoft Authenticator, can back up or sync your codes to a new phone. Check your app's settings before you need it.


3. No key, no phone and no recovery codes

If you have lost your app and your recovery codes, and have no passkey or security key, you can't get into your account without the help of SimplyPrint support.


We take the responsibility of account security very seriously, so like many other sites where you can enable two-factor authentication, we will need to see some ID to make sure we don't let a stranger into your account. An email from your account's address isn't enough on its own.


Send us an email with the following:

  • A picture of your passport, social security card, driver's license or other government-issued identification with your name on it
  • The picture must not be a screenshot or a picture of a picture
  • Send the email from the email address you use for SimplyPrint, to contact@simplyprint.io


We strive to respond within 24 hours.


While you're unable to access your account, you can always print via SD card or OctoPrint.
