securityd using a lot of memory; when killed, Airmail constantly pops open new browser windows for Google account login

I'll notice my fans whirring loudly and fire up Activity Monitor to see what could be causing the ruckus when there's nothing obviously causing it that I'm doing in the foreground. I see in Activity Monitor that securityd is running and using 100% CPU and 3+ GB of memory. I kill it, because most macOS processes are resilient and will come back if they're necessary. Immediately after doing this, I get a dialog asking me for my password to unlock the login keychain. Seems OK, so I proceed. Almost immediately after doing this, a browser tab opens to a Gmail login. When I fill it out and proceed, it's apparently for Airmail access to my Gmail accounts. This continues to happen until I reboot the computer.

I'm not sure if Airmail is the culprit in this, but it's been going on now for at least a month.

Airmail Version 3.5.3 (460)
macOS 10.12.6 (16G1036)

    i have 4 email address that i switch between to keep mail separate.

    suddenly i'm getting the browser popping up and asking for credentials everytime i switch after starting up. quite a time waster if not fixed.

    also the attached error pops up with each request to validate my account with google.

    it was driving me crazy. i considered going back to apple mail to get work done.

    but before resorting to such a traumatic change i decided to delete all the google accounts in airmail. also i removed the traces of airmail from in the 'manage apps that use google' restarted airmail and all is good.
