Password Screen Flashing on iTunes 12.7

This worked for me: I disconnected from the internet--on my computer, I unplugged the ethernet cable; launched iTunes; signed out of my iTunes account; quit iTunes; reconnected to the internet (plugged the ethernet cable back in); launched iTunes; and signed back into my iTunes account.

I tried doing a repair on the app via Win10 apps/features menu and no luck. Best workaround, which isn't a great fix at all, is to click cancel/X on the dialogue box and not input my password. Can't make purchases but you can use iTunes for your personal library already on the machine and add/remove tracks as usual without using the Store downloads. If you're just using iTunes for a music manager this is your best way forward until they update.

Aw no 😟

Take care ~

none of the suggested solutions worked for me. But connecting/disconnecting from the network while starting iTunes has eventually helped. Like someone above said "log in while disconnected" - you can't really do that.

Disconnecting from the Internet is the ONLY solution to this massive bug. THANK YOU!

nope didn't work....I disconnected from internet, now I can get to a functional itunes...another stellar DL from Apple and as usual its been over a month since it started and, no fix, no information nothing...

The restart the computer, and using the repair fixed the problem for me also.....

Ugh. I have the same issue. Neither fix worked for me--disconnecting from the internet or doing the "repair" download. It's completely non-functional and just locks up iTunes every time I open it. Apple, are you listening? HELP!

Same for me... what a pile of cr&p. Installed latest ITunes update and, bang, can't use the **** thing.

Looks like this thread running for over 1 month now... WHAT ARE YOU DOING ABOUT IT APPLE ?

For christs sake if you can't fix stuff promptly why not let people roll back your ****** software updates so that at least they've got a place to go back to until you get your act together

I have the same problem after downloading the latest update. I'm running Windows 7 Pro 64-bit. Tried a complete uninstall and reinstall of iTunes, but it did not fix the problem. I then tried disconnecting from the internet, which kind of worked and allowed me to log into iTunes, but as soon as I reconnected to the internet, I had the same problem. Seems to be some how related to the internet connection. FYI, I am using a wireless connection. Haven't tried using a wired connection.

Thanks Sk8Dream. That worked. Strangely it didn’t quite work the first time, but after I closed iTunes in Task Manager and then clicked on the short cut to reopen it, the password screen no longer flashed. Good job.

Thank you Sk8Dreams, I tried every other solution noted here and yours is the only one that worked. NB It didn't work the first time, I had to use the Task Manager to stop iTunes, but it's worked perfectly every time since then, thanks

I am going through same, what makes it worse is that I had forgotten my AppleID and HAD to wait 14 days for recovery - that in itself was infuriating ... NOW, when I setup my phone and go to Itunes to connect, I have had the flashing password too - I have uninstalled properly, restarted and reinstalled - all to no avail ...I am beyond frustrated

i can not believe apple would allow this bug to persist.

in my opinion: apple's software development team, and product owners, of the online/desktop apple itunes application seriously need to be TERMINATED.
