◆ Account cooperation to prevent spoofing
I searched for the user name and chatted earlier, but if I do not enter a profile, I can not be sure if that is what I really want. In the unlikely event that the profile was created for impersonation, there is also the possibility of getting into trouble while misunderstanding the chat partner. On the other hand, if the frequently updated SNS is linked with the chat service account, it should be easy to verify the identity of the account. Because the linkage between such SNS and chat service is possible in Keybase, this time we will work with Twitter this time. Tap "Prove your Twitter" on the user page.


Enter your own Twitter username and "Continue"


Tap "Tap to copy" and copy the text, tap "Tweet it now" and open Twitter.


Log in to Twitter


Tap the tweet icon ......


Paste the text you just copied and tweet it.


After confirming that you are tweeted ......


Return to the application and tap "OK tweeted! Check for it!"


Your account collaboration is complete


When searching "gigao" again, it is displayed that it is linked with Twitter, and it is easy to confirm the identity. This collaboration seems to play a part in preventing spoofing.
