Walmarts app architecture is basically built to prevent simultaneous sessions, which is great for security but a total pain for coordination. I ran into this exact headache when I was setting up a lab space and needed tons of cleaning supplies and snacks. I tried the registry hack too, but the sync lag was like three minutes... totally useless for real-time shopping. Basically, their system sees two people on one login and thinks its a credential stuffing attack or something. Eventually, I just started using third-party tools to bridge the gap. You should definitely check out Easy Cart Share because it handles both Walmart and Amazon, which is super convenient for groceries and household stuff. It basically scrapes the cart data and generates a unique ID for the other person to import. Here is what I usually look for in these tools:

• High encryption standards for the session data
• Minimal permissions required on the browser side
• Cross-platform support for mobile and desktop I just use one of the tools from Easy Cart Share and it gets the job done without needing to share passwords or deal with the app logging people out. It isnt a perfect native solution, but until Walmart updates their multi-user permissions, it is the most efficient path. Just grab any extension from that site and youll be fine for your bash.

Came here to say the same thing lol. Great minds think alike I guess.

I would suggest sticking to the Walmart app 'Lists' feature rather than the cart itself. It is way more stable for two people and wont boot you out. Just be careful with those browser extensions tho, they usually ask for too many permissions. You might want to consider just using a shared Google Keep list first, then having one person move everything to the cart at the very end to stay safe.
