All of my devices forget all wifi passwords about once a week

Me too. All family members. All devices (phones, iPads, MacBooks). Any WiFi (Multiple locations). Latest iOS versions. Seems to be a core Apple iOS issue not being resolved.

Pleas try what I suggested just above. Still going strong.

seems to be a keychain issue.

but what I did 11-5 still working

I am experiencing this as well. I have an iPhone SE on iOS 15.7.5, a MacBook Pro (2015) on macOS 10.14.6 (still using Aperture, so no upgrades to this machine in years) and another MacBook Pro (2021 M1) on 13.4.

In each case it has been the phone and the older MacBook where I have initially noticed the WiFi passwords being forgotten. The first incident was on the day following upgrading the newer MacBook Pro from macOS 12 to 13. The most recent incident (today) followed upgrading it from 13.3.x to 13.4 (about 34 hours earlier, in the early hours of Saturday 27th May). Once is happenstance; twice is coincidence—but if it happens a third time I will suspect enemy action…

Same here. All devices, about every week to ten days. Not router related because it forgets both home and work networks, and because my wife's devices are not experiencing the same issue. Just mine. Has cost me over a hundred bucks in data overages when I don't notice that my iPhone has forgotten wifi. Have a significant data package and have never gone over on data until now.

Ditto for me. Becoming progressively annoying. Happens a few times a week on both a Mac (v12.6.5) and iOS v16.5 (iPhone XR). Very surprised to not yet see more conclusive feedback from Apple Community Support.

I've also been dealing with this, for the past couple months. Two laptops and iPhone all forget the password and I have to re-enter it. It's not a home network or router problem, because somehow this doesn't happen with my husband's account.

You have to be persistent with them. Nearly all support departments operate on a tiered system. The bottom tier is intended to solve the simple stuff and keep the traffic away from Tier 2. If you run into trouble and can't get your problem solved, specifically ask for your "ticket" to be "escalated" to Tier 2 support, or ask for the "expert" with your issue. It doesn't work every time, but I've been escalated more times than not, because I do my homework first and do everything the first tier people would ask for already, and have those answers ready for them. Last time I called Apple it was about a Photos issue, I got escalated twice, and finally got someone to admit it's "broken" if you do a "pro quantity of images". The support guy even admited to using 3rd party media software.

Be persistent.

No changes were done to my devices (iPhone, iPad, and MacBook), and the annoying issue of reentering my password whenever I turn on my device started a few weeks ago. Passwords aren't being saved and it's really annoying.

Are you using the same Apple ID on all of your devices? YES

Have you made any recent changes to your devices? NO

Have you recently changed Internet Service Providers? NO

Does your router and modem require a firmware update? XFINITY AUTO-UPDATE

Apples evident lack of concern is a loud statement about how much priority iCloud Keychain has in their books. Not a single statement from Apple means they can be bothered to deal with a clear security issue.

Agree all devices including a new iPhone 14 have experienced this problem in my house and with my home Wifi. Every device gets kicked out where it seems to ‘forget’ the home Wifi password.

I tried all the Apple suggestions:

1. rebooting the router
2. updating all operating software on all my Apple devices.
3. forgetting my network and signing in again
4. rebooting every Apple device

The problem persists - likely an Apple problem.

I have the exact problem that everyone has mentioned, on all devices, for approximately the last month. This started for me the day after I got a new car with Apple CarPlay... does anyone think it could be related?

I don't have this issue but haven't updated to latest IOS. Perhaps it is hacker related network attacks causing password resets. These kind of attacks require local ~50-300ft access. Since Apple isn't helping maybe a pole of those following this thread of what city they are in.

Please respond with city. I'm in Torrance Ca but don't have the problem (yet ! )

So apple ?

does apple care cover me for when I loose my **** entering the same password on my work and home networks every other day and throwing my phone out of the window because you iOS is obviously flawed ?

I’m also having the same issue. This is so frustrating. I have been collecting passwords for years, so almost everywhere I would go, my devices would automatically connect to the wifi if I wanted to. Now I have to ask for the password and reenter it every time. Even in my own house, it asks for the password every single time 😣 please find a solution to the problem of so many users.

This is insanely frustrating. Happening on multiple devices, and it isn’t just on one WiFi network - also cannot share the password from another device on the same network, using the same Apple ID/iCloud etc, with whichever device is randomly forgetting it.

“It just works”. What a joke.
