I’ve tried uninstalling and reinstalling, but I still can’t login with companion app on iOS. It just flashes red but displays no error message. I can log into Arena and other Wizards stuff fine though.

I spent months doubting my own gut the late nights, the turned-away phone, the lies that felt like love. Then a PI used a legal phone spy, and within 72 hours, I had the truth: screenshots, call logs, deleted texts. My heart broke, but my mind finally rested. Stop guessing. Get proof. Start healing.

Still happens for me. I have a ‘+’ in my email address which I suspect is the issue based on the password solutions posted here. However you can’t change you email/username so I’m unable to use companion with my same Arena and Wizards account (which log in just fine)

UPDATE: Reset your password to be something WITHOUT Special Characters! That did the trick! (Thanks, @tmoretz#09284)

I created an account this morning (04/19/26), and I can’t login. Even after preforming password resets, I continue to get an error message about not having an account. But when I go to create an account, I get an error message that says I already have an account. *insert melting smiley face emoji here*

I have created a new wizards account with the same password and a different email. Now I can login. This was annoying during prerelease.

Was able to work around this issue as well after removing special characters from my password. Not ideal.

I have this problem today, i have strixhaven prelease in one hour...

I also had the same issue as of today and I tried pub#92000's solution and it worked on IOS. Yeah not sure why or what it was messing with but any & in your password seems to ***** it over for some reason

I also tried pub#92000's solution, and it worked on iOS. I also had an "&" in my password. Seems like some special characters are a problem.

I tried the solution suggested by user pub#92000, and it solved the problem for me on iOS

Same problem from iOS 18.7.7

Same exact issue here

Potential fix: I had to reset my password and set a new one. I’m guessing the problem is that I had an ‘&’ symbol in my old password, which has caused issues on other apps in the past. Either that or the length (was 22 characters before and now 18).

Anyone has found a solution for this?

With my Wizards credentials I cannot login to Companion

Still I can connect to MTGA or this Support site which confirms I know my credentials!

iOS 18.7.7
Companion 1.11.4

Please provide urgent feedback howto connect to companion

This happened to me last night! Hopefully a fix is implemented soon

Same issues here. On iOS and can login fine on web and arena, just not companion.

same issue and same experience as the other commenters. can log in to other wizards related sites and apps but can't log in to companion using the same creds. been going on for at least a week for me. please fix!

Same issue for me

I have the same error on the Companion App in IOS. The password is correct and I can login elsewhere, but in the App the loading wheel appears briefly and then nothing happens.
