git send-email and gmail smtp

[jim.cromie at gmail.com]

so I tried to submit a patchset via sendemail,

its been a while since I sent from this computer,
laptop power cord is cut :-(
but failure wording is ambiguous

5.7.8 Username and Password not accepted. For more information, go to

Essentially, google is changing policy,
and 2FA is coming (or just arrived)

is there a well-travelled path to work around this issue?

something like ssh-key-agent ?
