Not receiving the 6-digit authentication code in my phone

Shopify Discussion

Topic summary

Issue: A user could not receive the 6‑digit two-factor authentication (2FA) code on their phone when logging in via Shopify CLI (“theme serve”), forcing use of a recovery code.

Troubleshooting and observations:

  • Tried multiple browsers in incognito (Firefox, Chrome, Brave); consistently reached the 2FA prompt but no code arrived.
  • Believes it’s not an internet issue; suspects a possible mobile carrier problem.
  • Another participant confirmed their own 2‑step authentication was functioning, suggesting no widespread Shopify outage.

Current status/update:

  • The next day, code delivery resumed without any changes made by the user.
  • Root cause remains unknown; no official confirmation of an outage was provided in the thread.

Outcomes and suggestions:

  • No concrete fix or action item identified; resolution was spontaneous.
  • The user recommends Shopify offer additional authentication options beyond mobile phone numbers and recovery codes.

State: Resolved for the original poster, but with unresolved cause; suggestion for improved authentication options remains open.

Today, I attempted to use Shopify CLI and ran the “theme serve” command on my local side. However, I encountered an issue where I was prompted to log in as usual.

This time I did not receive a 6-digit authentication code on my phone, which resulted in me getting stuck on the login page. I want to clarify that my phone is capable of receiving Shopify authentication codes since I successfully used it for login purposes just 3 days ago. Due to this situation, I had to resort to using my recovery code to log in.

I’m wondering if anyone else has experienced similar authentication problems today. Additionally, I would appreciate it if someone from Shopify could confirm whether the authentication service is still functioning properly or if there is a temporary shutdown.

Hi @Surbhi_Dudhe ,

Thank you for confirming that your 2-step process is still functioning properly.

I have already attempted to access the login page using three different browsers in incognito mode, including Firefox, Chrome, and Brave. In each case, I was able to reach the page where I am prompted to enter the 6-digit code. However, I have not received the code today.

I don’t think this issue is related to my internet connection. But, perhaps it is a problem with my mobile carrier.

Just to update the status.

It works again today and I totally have no idea why it is fixed. I think Shopify should provide other authentication options rather than using mobile phone number and recovery code.
