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

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…

I'm also on a 2019 16" Mac Book Pro with macOS 10.15.7. My iPhone and iPad are on the latest iOS/ipadOS. I have exactly the same issue with WiFi password randomly forgotten on any of the devices. It's not a network issue as my WiFis have worked without issues for years. I also suspect an iCloud bug corrupting the keychain introduced with the latest system updates. I believe the fix should come from Apple themself.

Also same issue: on newer gear - MacBook Pro M2, iPhone 14Pro, iPad Pro, AppleTVs - all on most recent OS for each device, and older MacBooks, iPhone 12, iMac all on latest OS possible for those devices. Home Wi-Fi is Orbi router, unchanged settings for 3 years. Suddenly we have to enter PW for Wi-Fi across all these devices, every couple/few weeks. Devices are on iCloud Keychain, so assuming the issue stems from that.

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.

Same issue for me, I have several Mac, iPhone, iPad, HomePod ... I roam between several networks (home, office, my parent place ... ) and about a month ago all my devices started to forget their wifi password. For instance, I am using HomePod to manage my home automation when I am away. Then suddenly I receive message on my iPhone that the HomeKit app is not working. When I come back home I have to re enter wifi password on all my devices and re install all HomePod to the network, this is a total mess. This is most certainly linked to an issue with iCloud and Keychain, since the "deletion" of the wifi password can happen when I am away and it propagates to all devices.

For info I ran a Wifi diagnostic on my macbook and it is reporting "conflicting country codes" ... maybe related, maybe not ...

Just chiming in to say me too. I've been to Apple support multiple times about it, the non-solution is to make wifi connections private. This sometimes makes them hold a bit longer but it's not a fix, and I don't think there is an option to do this on MacBooks. Apple have had me reset all settings on the iOS devices, hasn't fixed the problem and has just been a complete hindrance having to put it all back to rights again at a later date. I feel like it's been a good few months of this for me.

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.

I haven't, but you're probably better off going to the Genius Bar. My experience with Applecare over the phone is getting people who follow cookie-cutter protocols that won't work and only fix basic stuff; mostly errors on the user end. With something like this, you might run into somebody who knows there stuff at the genius bar, and they can either help you or report to apple that something is causing some users to have a corrupt keychain account on the cloud, if that is the case. But it seems like not enough people have this problem for apple to address it. When I get the time, I'll go to the genius bar.

apple support is surprisingly silent. i twitted and they usually respond but not this time. i suggest tweeting and retweeying.

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.

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 ! )
