This is a known issue, due to updates to the browser extensions for LastPass and 1Password. Unfortunately, these extensions ignore our system's coded identification of signature blocks.
We have been in touch with developers at both organizations, and per their documentation, the only way to solve this auto-insert issue is for our users to edit the extension settings and turn off the setting that 'automatically fills login information'. You can do this for just our domain (app.getincontract.com) and this does not turn off the extension overall, you can still elect to fill or insert credentials with a single click wherever you specify. All this does is turn off the extension's ability to automatically insert your email/password wherever it thinks a system is asking for those credentials.
