App password Gmail/Outlook

W1zardK1ng

I decided to setup my old gmail and outlook email on my phone using K9-Mail app.
Since i don't want to login using a browser while setting up the accounts i decided to use the app passwords.
Everything works fine now but, in google documentation it says App passwords aren’t recommended and are unnecessary in most cases. To help keep your account secure, use "Sign in with Google" to connect apps to your Google Account.

Is app passwords are any way less secure? Is it fine to use as an authentication in mobile or the Sign in with Google option is better?

App passwords are less secure than Sign in with Google, yes. In Vanadium, You can enable Open external links in new incognito tab, Sign in with Google for K-9 Mail and then disable It.

[deleted] why so, app passwords are one time use, so it should be much secure i was thinking

W1zardK1ng App passwords are not for one-time use I think, and Services/Apps with access to your app password can do anything to your Google account.

Btw You can learn more about "Signing in with app passwords" on https://support.google.com/accounts/answer/185833

The app passwords are not one-time use as already mentioned by @[deleted].
This is a solution for older apps not compatible with modern authentications. And usually used for apps that don't support MFA, etc.
