I would like to second this feature request. It is not uncommon for corporate Single Sign on applications to require username and password + TOTP.
Given the following values:
Username: rallour
Password: mypass
TOTP: 323813
The login form would then be filled in with the following:
Username: rallour
Password: mypass323813
The way I would like to see it solved is to be able to use a template for the password field. This would allow me to combine two arbitrary fields (a static password, and a dynamic TOTP) to create a password field that is a combination of both the password and TOTP as the value, and then have that templated value be what is auto-filled into the form.
RIght now it works with multiple selection and copy/paste steps, but it'd just a nice quality of life feature as I end up needing to do this multiple times per day supporting different customers, all of which require the format of username / password + TOTP.
Thanks for a great product, and especially thanks for supporting it on Linux!
