Remember Me no longer working on Safari 12

Hi all,

The remember me checkbox is no longer able to be checked on Safari. This happened quite recently, so I think it began with Safari 12.

I have tried turning off both the “Block all cookies” privacy setting and “Prevent cross-site tracking” settings in Safari, no no avail. Duo will complain that “you need to enable cookie to use remember me”

The issue is specific to Safari. Remember Me still work on Firefox and Chrome on my Mac.

Safari users are reporting this issue with other sites too, not just Duo. It is possible that the issue is related to the version of the Mac OS or iOS, not the version of Safari, as someone on this thread suggests


I’m seeing this, as well, at my university workplace. This is only happening with Safari and macOS Mojave. Other browsers in Mojave are fine; other macOS’s Safari have no trouble; and so far it seems as if the Remember Me/Safari cookies function works fine with other non-Duo requiring sites.

I’ve tried every relevant combination of Safari cookie settings, all to no avail.

Hi. See

Looks like a fix will be coming next month.


I definitely remember reading on the page that you linked that a fix was coming on a specific date in December (sometime during the first week, if memory serves). But that same page no longer mentions a forthcoming fix at all.

It just suggests the only functional workaround: allowing all third party cookies. I don’t doubt that a better solution will be difficult. Safari’s updated ability to effectively and aggressively block tracking cookies is already legendary:

Since Apple introduced what it calls its Intelligent Tracking Prevention feature in September 2017, and with subsequent updates last year, advertisers have largely lost the ability to target people on Safari based on their browsing habits with cookies, the most commonly used technology for tracking. One result: The cost of reaching Safari users has fallen over 60% in the past two years, according to data from ad tech firm Rubicon Project. Meanwhile ad prices on Google’s Chrome browser have risen slightly.

That reflects the fact that advertisers pay more money for ads that can be targeted at people with specific demographics and interests. “The allure of a Safari user in an auction has plummeted,” said Rubicon Project CEO Michael Barrett. “There’s no easy ability to ID a user.”

So I’m certainly not going to turn all of that off, just to work around a problem that Duo needs to address.

I’m hopeful that Duo is still working on a solution, but has discovered that their original solution (and timeline) wouldn’t do the trick. But that hope isn’t based on any information I have from them, just my experiences with working with them in the past.
