Hello @maria gomez I hope you are doing well,
Please follow this guide in order to resolver your issue : https://support.microsoft.com/en-us/account-billing/i-can-t-sign-in-to-my-microsoft-account-475c9b5c-8c25-49f1-9c2d-c64b7072e735
I'm going to resume here what happened;
After resetting your password, repeated sign-in attempts may trigger Microsoft’s security measures, temporarily blocking your account and causing an infinite loop. This lockout is designed to protect your account from unauthorized access, so when you encounter a “too many attempts” or “sign in blocked” message, it typically indicates that the temporary security threshold has been exceeded. In such cases, waiting for the lockout period to expire, clearing your browser’s cache and cookies, or trying to sign in using an incognito window or different device may resolve the issue.
Sometimes just waiting 15 min is enough
If these steps don’t help, you should use the “I can’t access my account” option to initiate the account recovery process, which may involve additional verification methods such as security questions, alternate email, or phone verification. In addition, double-check that you’re entering the new password correctly (ensuring that saved credentials aren’t auto-filling an older password), and if the problem persists, contacting Microsoft Support directly with details of your issue can aid in unlocking your account.
