… are using Unified Login systems that require persistance of “YOUR ID” ( ie hardware, ‘metadata’, software, security tokens = the badge that your browser shows to the Eco-System Gate House) across the Eco-System’s websites.
And, the ‘YOUR ID’ persistance requirement now forces Eco-System account holders to LOWER personal (the browser and to some extent, your) protection shielding afforded by the browser.
So, now what you encounter, is “expected behavior” ← your having to lower Brave Site-Specific Shields (or certain features thereof - sometimes only necessary to allow all cookies, for example - or disable only the blocking of fingerprinting, as another example).
Dental X-Rays not yet required. Though Cloudflare’s involvement, increases chances of the browser being caught up in barbed wire.
On Windows 10, the only way I can get to my Yahoo Mail Inbox in Brave is to have shields down in Brave and have all the ads, which I don’t want .On Windows 11, if I accept third party cookies, and shields stay up, log in works fine-Jack
Update: I cleared all Yahoo Mail cookies and set Brave to “Accept all Third Party” cookies. The password screen after entering the password is very, very, very, very slow. But I can get logged in. I plan to stay logged into Yahoo Mail in Brave as much as I can until this is resolved. To reaffirm. all this slowdown started yesterday on both PC’s. Brave was always lightning fast on both my Windows 11/Windows 10 PC’s. on Yahoo Mail -Jack
Are you having trouble logging in at other sites? Test other accounts.
Create a new user Profile for Testing:
Create and use AN ADDITIONAL Brave Browser user Profile (Menu --> More tools --> Add profile) - only ← meaning: Do not have any other Brave Browser user Profile tabs/windows open.
When creating this new Brave Browser user Profile for test purposes
Do not import anything.
Do not add any extensions.
Do not allow/enable any Brave Browser “bells and whistles” such as Brave Rewards, Brave Talk, etc.
IF this test Brave Browser user Profile does not present your problem, then possibly, the profile that you have been using, has a problem . . . and that might be caused by one or more extensions, or too many tabs ← complex/conundrum.
Extensions Tests:
test by disabling all extensions
test by enabling each extension individually
test by uninstalling all extensions
test by installing each extension individually
test combinations of extensions
test order of installation of extensions
Brave Support - re such an issue as yours - will probably not be around until after this weekend.
I am using Brave Browser to visit https://login.yahoo.com and also examining/monitoring that site via the browser’s Developer Tools > Network window.
One source related to Yahoo’s Unified Login system, is consent.cmp.oath.com and that is blocked ← despite my having incrementally lowered Brave Site-Specific Shields in addition to simply setting Site-Specific Shields: DOWN for the Yahoo login site.
The cmp in consent.cmp.oath.com stands for Yahoo’s Consent Management Platform.
Re the oath part → “Oath” was the former brand under Yahoo / Verizon Media, and that CMP endpoint is used to handle things like:
GDPR / privacy consent flows
Cookie preferences
Legal acknowledgment before authentication proceeds
Other than the testing:
other site logins, to see if something in general is a problem
a new Brave Browser user profile
extensions
And Reset permissions for sites:
www.yahoo.com
login.yahoo.com
login.aol.com ← part of the Yahoo Eco-System
… I do not have suggestions for what you could try, in order to help narrow down where the problem lays as a potential bug/something for Brave to fix.
You may get a response from Brave Support, early in the coming week.
Thank you for the Kind Words! Things are improving!
Need to report that there are no other issues with other sites. In Brave. Just Yahoo Mail log in. There is about a 20 second delay before the whole Yahoo Mail log in screen loads in Brave. The delay of Yahoo Mail loading the login screen seems to be the culprit, which was not an issue before April 17, 2026. No other changes to settings or PC other than what I have reported above.
If you get curious about discovering more, you might explore the Brave Browser Developer Tools (aka DevTools) window:
You can easily dismiss this detective work, but you might discover some important info that will help resolve your issue. Also, when you have questions about what you see, present your questions to an AI service online - ChatGPT, Netify AI, and Perplexity.ai are what I currently use.
In a Brave Browser New Window, go to: https://login.yahoo.com
Over at the upper-right corner of the browser window, there is a “layered” 3-horizontal-lines, “hamburger” icon ← click on that, to get a lengthy pop-down menu. Scroll down that menu and select More Tools. An associated pop-up window will display. Click on Developer Tools:
Over at the upper-right corner of the Developer Tools frame/window area, is a vertical 3-dot icon ← click on that. A small pop-up will display, showing options for the arrangement of the DevTools frame/window. Select the 1st (ie left-most) of 4 options:
Reload the https://login.yahoo.com webpage ← by using keyboard shortcuts (F5 or Ctrl + R on Windows; Cmd + R on Mac). (You do not have to leave the DevTools window’s front-most position.)
Further down the DevTools window, select the Console tab:
I suggest that you add columns, so you can view the whole DevTools > Network tab window as follows. Those individual lines (under the column titles) are typically called network requests (or just requests). More precisely:
Each row represents a single HTTP request/response transaction.
In DevTools (including Brave/Chrome), the whole table is often referred to as the Network log.
Each entry can also be called a network entry or request entry.
Q: Using Brave Browser and wanting to login at https://login.yahoo.com, I have the Developer Tools > Network window open. I have among the columns, a column named Server. In that column, there are many entries of ATS ← I wonder what that is?
Answer from ChatGPT:
In your Brave DevTools Network tab, the Server column shows the value of the HTTP Server response header - basically, what the backend identifies itself as.
When you see ATS, that’s almost certainly referring to Apache Traffic Server.
What that means in practice:
Apache Traffic Server (ATS) is a high-performance caching proxy and CDN edge server.
It’s often used by large companies (like Yahoo) to:
Cache content closer to users
Route requests efficiently
Improve load times and reliability
So your request to login.yahoo.com is likely being handled (or passed through) Yahoo’s edge infrastructure running ATS, rather than a “raw” application server.
Re what I had here, about consent.cmp.oath.com ← I have removed, because I discovered that particular item was blocked by some filter in my network AND also blocked by not allowing all Trackers * Ads in the Brave Site-Specific Shields settings.
Your initial post reports you’re using Windows 10. I’m using linux (specifically: up-to-date Debian), but I don’t think — for this issue — different operating systems are relevant. Very likely: there WILL come a time when an increasing number of websites won’t be responsive if you continuing to use a no-longer-supported operating system.
If you review “Related Topics” listed below replies to your query, you’ll see: difficulty logging into Yahoo isn’t a new issue.
Specific to logging into Yahoo mail: it can be easy or twitchy. “Easy” requires no explanation. “Twitchy”: Yahoo heavily promotes (but at this moment doesn’t actually require) using passkeys or 2-step log-in. I avoid the former, and when Yahoo requires a 2-step log-in, I obtain the random 6-digit sequence with an alternate e-mail provider known to Yahoo. For whatever reason, it’s been a few months since I last encountered this request from Yahoo. You report that logging into Yahoo is slow. This IS consistent with my experience.
I’ve had this experience using both Brave and Firefox.
Your initial post (and follow-ups) didn’t mention if you have any extensions installed which may not be playing well with Yahoo. I do have both No-Script and uBlock Origin installed and I use BitWarden as my password manager in both browsers. These extensions don’t impede my logging into Yahoo, but other extensions could present an issue. Do you have any extensions installed that are active when you attempt to log into Yahoo?
I hate Windows 11 and plan to keep Windows 10 with third party security options on the machine with Windows 10. MS is getting such a backlash about Windows 11, that they may possibly extend the ESU updates. I am not worried about Yahoo phasing out of Windows 10 for a long time. Not with about 45-50% of the world still on Windows 10.
Anyway, no other extentions. Brave is so good that it doesn’t need them! But Yahoo can be tricky with things. This was a similar issue reported with Yahoo Mail and Brave a few years ago. Yahoo is like the only site that does this. I love Brave!
I have Firefox with Ghostery and no problems with Yahoo Mail there. Oh and yea, my ten year old Windows 10 PC is twice as fast as my two year old Windows 11 PC! LOL!
I don’t want to compromise turning off the excellence of Brave’s security and anti-tracking just because Yahoo is a little slow on the log ins. Waiting for an update from the Brave Browser or from Yahoo to fix this, I think is the best solution.
