While at the login screen for my Google account, I pulled up my password manager and began entering my master passphrase, so that I can retrieve my password for the login. However, while I was looking at the keyboard and typing the master password, I must have accidentally tapped my touchpad, bringing the Google login into focus. As a result, I had typed the entire master into the Google page, though none of my keystrokes registered as dots in the "Password" field.
I am now concerned that the login page may have still captured my keystrokes and that Google may have my master password, which I also use to encrypt files.
Should I change the master? Or am I being too paranoid?
