I'm sorry this happened to you, but don't be so surprised. Phishing and MITM attacks are alive and well, and 2-FA is just a bandaid for bad password practices. You might do well to check on dehashed.com for your own credentials. Source: over 1 year ago

2 useful resources are: dehashed.com and https://github.com/hmaverickadams/breach-parse from heath adams. Keep in mind that it is not a good idea to use these in an unethical way. Doing illegal stuff can and will get you in trouble. Source: over 1 year ago
