Hi AB,
Thank you for reaching out to Microsoft Q&A forum.
I am sorry to hear about the incident you encountered while trying to sign in to your Microsoft account. Please follow the steps below (recommended to perform them in an InPrivate/Incognito window to avoid old autofill or cached data):
1. Enter your full email address correctly
- Please ensure you enter the complete email address (e.g., ******@outlook.com, @hotmail.com). Missing the part after “@” may cause the system to say the account does not exist.
2. Bypass device/PIN verification and sign in with your password
- If you see the message “We couldn’t use your device to verify your identity…”, select Next > Sign‑in options > Password to sign in directly with your password.
3. Forgot your password
4. If the sign‑in box auto‑fills a strange/random username
- This usually happens due to old cookies, tokens, or autofill. Please open an InPrivate/Incognito window, turn off any extensions/password managers, and try again.
About the 7q6ca tag: This is a sign-in flow interruption that has been reported by the community, often occurring when authentication through Windows Hello or an old token becomes stuck. Skipping device verification and trying again in a private browser window usually resolves the incident.
Since this is a public forum, we will hide your personal identifiable information, and I have sent that image of yours containing your personal identifiable information in a private message so we can work together to resolve the issue. Also, please check your private message in case you want to share another screenshot to avoid leaking your PII by click on the Private Message button as show below
