Web Visitor Login + Resume Previous Conversation Feature Added

You can still do everything, like chatting or viewing posts, without logging in.
But to expand participation features like comments and guestbooks in the future, I've added a visitor login function.

You can also view previous chat records divided by session, and click on a session to resume the conversation.

Lately, I've been studying the pros and cons of various security authentication techniques, so I applied what I learned to managing my web page accounts.
Instead of 'passwords,' an anachronism that is impossible to manage safely with the human brain,
I applied a login method using Passkeys.
You can easily sign up and log in using the Passkey supported by your device.
No email address is needed; the name (nickname) and device name are optional fields for convenience, so no personal information is required at all.
