Sudden pop up

I was chatting with suspicious person on messenger. He send me a voice message. As soon as I tapped on voice message  the window appeared. The window from setting>passwords. I was holding my phone that is why against my will I unlocked this window and all my passwords appeared. Then suddenly this window disappeared. I think someone remotely logged into my phone. If there is a chance that it is a bug and anyone has an experience please let me know 🥹🙏🏻❤️ I can’t contact support, it’s not available in my region
