Honeypot sure I didn't think of that.. But I was under the impression the FBI confirmed it ? So we can rule it out.
Making the password impossible to guess - how could that not be?
Since then you know you have a breach, as its randomised gibberish, if you then get the 2nd device asking " is this you trying to login " you can definitely know you are compromised....
I can't see your logic here, that isn't " theatre " ????
If you think that is theatre what is better then? Words and numbers.. easily brute forced.. Sorry can't agree.
Why would they willingly destroy their successful honeypot if the other party announced they've access to it?
I haven't seen what's in it either though, but I would not rule it out yet, especially when the FBI is involved - which love those tactics
When you're compromised, changing the password is obviously not theatre - but changing a password which is randomly generated with enough entropy is what's pointless theatre. A secure password is secure, esp. If you're already using a password manager then the act of changing isn't meaningfully increasing your security (unless you're aware that your password was compromised) because the way to compromise it is what...? Having a keylogger on a device you logged in on? Then the changed password will be just as compromised
