Introduction and catchup

Libsecret's secret-tool utility
The password manager package that is being used here is called secret-tool and is part of the libsecret tools package. Documentation on this tool is available from http://manpages.ubuntu.com/manpages/focal/man1/secret-tool.1.html.
To save a password:
(when prompted type in the password you want to store)
To verify that the password has been entered correctly:
secret-tool lookup host smtp.gmail.com
Modify the /etc/msmtprc config file:
sudo nano /etc/msmtprc
replace password line with
passwordeval "secret-tool lookup host smtp.gmail.com"
To use Microsoft rather than Google SMTP
Check the Sync option in your outlook client for the SMTP settings. The port and server name are retrieved from here.
An app password needs to be generated from within Microsoft and stored in the secret-tool vault.
/etc/msmtprc needs to be modified to cater for Microsoft's SMTP server.
