Hello @Moreira, Daniela,
Thank you for reaching out to Microsoft Q&A. I'm sorry to hear that you're having trouble accessing your sandbox and managing your accounts.
Here are some steps you can take to resolve this issue:
- Reset your password: If you're having trouble logging in, try initiating a password reset for your account. Check your email for password reset links or instructions. Make sure you're checking the email associated with each account.
- Check Spam Folder: Sometimes, password reset emails can end up in the spam or junk folder of your email account. Be sure to check there as well.
- Clear Browser Cache: If you're not receiving the authentication code, it may be due to issues with your browser. Try clearing your browser's cache and cookies or using a different browser to see if that helps.
- Check Authenticator Settings: If you have two-factor authentication (2FA) enabled, make sure that your authenticator app is working correctly and synced with your account. You may need to check the settings in the authenticator app.
If you are still encountering the issue, feel free to contact us for further assistance. We are happy to help you.
