When you sign in to Skype with your Microsoft account, you might be asked to add security info to your Microsoft account.
Don’t worry, there’s nothing wrong with it, we just want to make sure your account is always protected and that you don’t lose access to it, so we need to verify your details once or twice in a year.
The following questions and answers will help you with the verification process:
If you don’t provide the security code you’ve received to verify your Microsoft account within 7 days, your account will be locked out. The reason is to protect it against misuse.
If your account gets locked out, simply repeat the verification process. After you provide the security code, your account will be recovered.
If you haven’t verified your Microsoft account for more than six months, a new verification is required to make sure that your account is secure and you’re the only person that accesses it.
