Windows 10: What is gMail's Mail App Password

I have a number of gMail accounts. When I look at my security settings in Google. I see 3 entries for each account..

Mail App Password
Thunderbird (which I'm moving away from)
Mailbird (which I'm moving to)

I'm curious about the first one, Mail App Password. It seems to have been created approx 2 years ago. But I cannot think what it could be for? As far as I know, I don't need Mail App Password unless it is somehow associated with the Thunderbird and Mailbird emails. If I delete it. Will my Thunderbird/Mailbird programs still have full access to my gMail Accounts. Any light shed on this would be helpful.

I also have 2 step authentication on for all accounts. I assumed this was for verifying me as a user. But I'm wondering if Thunderbird/Mailbird need some settings to cope with logging on with 2 step authentication?

My basic problem is I cannot see any differences in google for all of these accounts. But some of my Mailbird accounts won't send mail. So maybe there is a setting in Mailbird, which I've overlooked, for why this is happening?

Windows 10 Mail forgets Gmail password almost every day

Reason

Windows Mail app keeps prompting for Gmail account password frequently with the "your gmail settings are out of date" message—
According to a comment on this post . . .

Potential Solutions

Based on some quick research there may be two options that may help resolve this. . .

1. Enable the 2-Step Verification functionality and security feature with your Gmail account and then use the 2-Step Verification to verify and trust the Windows Mail app to have access to your Gmail account
   
2. Enable and use the Less Secure Apps functionality by turning that ON and using your usual Gmail account password with the Windows Mail app to authenticate

Where did you get that message about mail app isn't supported? And to create application password? Can you post a picture of it?

I'm using gmail account in Mail app with two step verification and all I had to do was confirm password and second step verification.. All went smooth, and I'm getting mails in multiple Windows PCs and phone.
