Less Secure Apps Gmail Setting Not Showing. The good news is Google did not block access completely. They still allow Basic Authentication for these “less secure apps” to work with Gmail. The only thing is you must explicitly enable Basic Authentication via the Allow less secure apps option in Gmail. There are two ways to access the Allow less secure apps option. Both require you to. Make sure your antivirus/firewall software does not block Mailbird: disable it and try again. Gmail users: try to switch from oAuth authentication to Username & Password and enable less secure apps. If you use 2-step authentication this should be the other way around, switch from user name and password to oAuth. Third-party sites & apps with access to your account. Recover your Google Account or Gmail. To review and adjust your security settings and get recommendations to help you keep your account secure, sign in to your account. Sign in. Help.

If you use 2-step authentication this should be the other way around, switch from user name and password to oAuth. MY SERVER SETTINGS ARE NOT THE ISSUE! I HAVE ALREADY DONE THAT, AND MUCH MORE. I'm simply trying to find the option I should see to "Allow apps that use less secure sign in", which I cannot find, in hopes that that might solve the problem. I'm fairly sure it's an issue on Yahoo's side, as it has been far too regularly over in the past 20 years.
One other thing you may have to do is change a security setting in Google to allow access to less secure apps. Google now considers the Windows Mail App a less secure app and therefore blocks it from doing some tasks. If you are concerned with this and while we wait for Microsoft to sort this out it might be safest to only use Gmail via a.

If you use 2-step authentication this should be the other way around, switch from user name and password to oAuth. Unfortunately, when less secure apps are not allowed, Outlook can't connect to Gmail servers, unless you also enable two-factor authorization then use an app password in Outlook. (The app password is a one-time use password that can be voided if you suspect it is compromised, without affecting your “real” password.) It would be a good idea not to use that same password for other logins, but that is just good practise and applies to any password for any login. Google/gmail calls apps that don't support OAuth2 "less secure". But, that doesn't make them insecure. So what it means is gmail's meaning of LessSecureApp is basically anything that doesn’t use OAuth2. Unlike with G Suite where the regular account email and password will authenticate into smtp.gmail.com if you turn on “allow less secure apps”, for regular Gmail accounts, you need to set up an app-specific password to authenticate into smtp.gmail.com. I consider this a loophole in Gmail’s policies, because I don’t believe this is what.
