I was just supposed to export a Twitter convo but the exporter extension didn't work because of some error. I contacted the creator of the extension and they asked for the link, and I stupidly copy-pasted the link from the extension, which has the direct URL to that chat session and also the private keys.
He immediately deleted my message and warned me not to share private keys, but it was already too late since he already managed to copy it so he can test the error on his side.
I want to trust that he won't do anything about it but I'm still concerned. I already have 2FA enabled on my account and also changed my password and my chat encryption key, but upon rechecking the link from the extension again, the private keys didn't change.
Am I actually screwed or there's still some way to change those keys or anything at all that I can do to prevent them from accessing my account?
