Safari 15 keeps logging me out of several sites every week or so

For others that are experiencing this issue -- can you confirm if the following steps reliably reproduce the issue for you?

1. Open Safari and login to Gmail
2. Open Safari Dev Tools (option + command + i)
3. Reload the page (command + r)
   1. Result: you should still be logged in to Gmail at this point
4. Open a new tab (command + t)
   1. Result: you should now mysteriously be logged out of your google account in the original tab

I've found a solution. Get rid of Safari and install Opera.

With these leads in mind it shouldn't be too hard to find right?

Have you submitted feedback to Apple?

— this is not true. I have this problem also on imac on intel

I'm still having this problem and I've restarted multiple times. I'm up to date with Safari and Monterey. It's really disrupting my work flow. I'm getting logged out of absolutely any website that requires a login session multiple times a day. This includes

• All google sites
• All Atlassian sites
• Lucid chart
• Amazon

Just to name a few of the common ones. This started immediately with the Safari 15 update. I have changed zero security or privacy settings from 14 -> 15.

Same here, same issue. For me it happens immediately after opening the developer console / web crawler and as a developer this very frustrating. I've been forced to go back to chrome for certain parts of my web development now since I don't have time for these problems as soon as I need to monitor my data. But I would rather see that Apple fixed this like yesterday!

NOOOOOOOOOOO.

Almost half of a year with this persistent bug, and there’s still no fix with this MAJOR update?!

My solution has been to disable Safari’s Web Developer tools and to only use Chrome for development. But sometimes I have to debug an issue with Safari, which means losing all my login sessions on major tech sites.

I can’t believe Apple’s own web developers haven’t torn down the door to Safari’s engineering department.

I have the same problem, although not every week or so but rather several times a day – this does not feel good. I am fairly tech savvy and had "everything security and privacy" under control, I definitely don't like it when software overrides my previous settings without consent.

Hello there radozd,

Thanks for posting here on the Apple Support Communities! This is a place where other Apple users can submit questions or respond to others to help lend a hand. Let's take a closer look as we do our best to provide some additional insight.

We understand some websites require you to sign back in more often than you're used to. Typically, this is controlled by the cookies or security settings as directed by the website itself. However, let's make sure Safari is set up to make sure they stay logged in as long as possible.

To get started, have you also tried completely resetting Safari by clearing all Safari history? We can do that by selecting Clear History from the Safari drop down menu next to the Apple icon.

Also, be sure to test with other Safari settings by going to Settings > Privacy. Some settings that help further protect your privacy and how websites can track you, can also lead to them signing you out sooner than expected: Change Privacy preferences in Safari on Mac

We hope this helps get you pointed in the right direction.

Take care.

I may just be lucky, but after nearing a year of this problem I followed the first two steps in this post on the developer forums explaining how the user there fixed it by:

Resetting all experiments: Develop -> Experimental Features -> Reset all to defaults

Re-enabling Safari -> Preferences -> Privacy -> enable "Prevent cross site tracking" + enable "Allow privacy-preserving measurements of ad effectiveness" (I suspect this is the issue but not sure)

I initially had several sites log out once, but I haven't experienced any further unexpected logouts in over a week, even when using the console/inspector. I hope I didn't just jinx myself 🤞

I'm running Safari 16.1 on Ventura 13.0 and a 2.9 GHz Quad-Core Intel Core i7.

I can't recall whether I tried the Web Inspector with all extensions disabled and still had this problem. Maybe there is a correlation to one. On the off-chance that this bug is caused by an extension here's what I have enabled:

• Adguard
• Cascadea
• Open in IINA
• Keepa
• Subscribe with Reeder
• Sponsorblock for YouTube
• Tampermonkey
• uBlacklist

same issue here. i'm logged out of major websites multiple times every day. how does this issue make it into a stable release?!

I’ve had Safari’s developer tools enabled since early April and somehow enjoyed a nice two-month spell that was free from this pestilent bug, but I suffered a relapse an hour ago after running some snippets of JavaScript in the console. My first clue: performing a Google search and noticing that the background color was white when my search results loaded. I’m a dark mode user, so I braced myself for the fallout: as expected, all my sessions with Facebook, Twitter, LinkedIn, GitHub, eBay, Amazon, and Gmail were gone.

Logging back into most of these sites results in a raft of security alerts that arrive via email and/or push notification. They all say variations of the same thing: “a login was detected from a new device we don’t recognize.” They usually contain links to the site so you can take immediate action to change your password. Somehow Google’s security page knows the name of my machine (SBP) and puts a little blue checkbox next to it, identifying it as “this device”. How Google ascertained that bit of private information is an alarming head-scratcher. Yes, I am logged into Gmail under “Internet Accounts” in macOS, but it’s curious how Google is able to correlate that connection with a “new device” it did not recognize minutes earlier.

So all of these big technology companies must be using a device-based login technique that relies on some kind of fingerprint they derive from the information Safari gives it, probably a hash generated by JavaScript from a number of factors. And somehow interacting with Safari’s web developer tools can corrupt that fingerprint and make us a total stranger to major tech sites.

I’m a web developer, but I only work on small-time sites that use unsophisticated cookie-based login sessions that have been around for decades. These types of sessions are still working fine in Safari 15. I would love to hear from a developer who works on big-time tech sites that rely on device-based login techniques. Their insight would be interesting.
