External file sharing

Question

When sharing the file with an external Gmail account, it asks for a security code to access the file. However, when sharing the same file with an external Microsoft account, it allows access without any security key. What could be the reason behind this, and how can I fix it?

this is my settings:

Hi @Vishnu Anand,

New and existing guests scope sharing will require people who have received invitations to sign in with their work or school account (if their organization uses Microsoft 365) or a Microsoft account, or to provide a code to verify their identity. Users can share with guests already in your organization's directory, and they can send invitations to people who will be added to the directory if they sign in.

If you share with a person who isn't in the directory(i.e., Gmail.com, Yahoo.com, etc.), they're sent a one-time code that they can use to verify their identity. See Secure external sharing in SharePoint

Depending on the security it turns out to be a by-design one. We are unable to disable code verification. As a workaround, you could set the sharing scope to anyone

This setting will allow users to share files and folders by using links that let anyone who has the link access the files or folders without authenticating.
