    Love your podcasts and tutorials. I have been a fan ever since I found you in 2013 or so.

    I agree with your ideas on Passwords. I have been caught several times trying to login on somebody else’s computer and had to try to enter a strong password manually. After 20 or so tries I gave up. I was reading from my password manager and there was no way to copy and paste. This problem also pops up when logging into streaming services on TV. This is getting better though.
    Thanks in Advance

    Love this series on Mac security.

    my only question is which Mac OS are you using for the demonstration ?

    thanks.

    Russell: I always use the current macOS for my tutorials. In some cases I am showing macOS Monterey, but I always mention that.

    Hi Gary. Excellent video’s and tips as always. Thank you. Two questions please: #1- With an authenticator app like Authy, once it’s set up and being used, are the codes generated by the actual app, or are they sent to your app by the service you are signing into like Amazon? #2-Is it possible to save (in Mac keychain) passwords for apps like authy that don’t have a user name or website to access them from? Thanks in advance. Kathy

    Kathy: The generate the codes. The idea is there is nothing for an attacker to “intercept” at any point. You can use the Keychain Access app to save miscellaneous things like passwords or even notes. But if you want more features, look to a third-party app like 1Password, which will also generate codes like Authy does.

    Hi Gary, Just to clarify, when you said ‘they’ do you mean mean Authy generates the codes? Is it done directly from the app? Re keychain and saving app passwords, would that be through the secure notes feature accessible on Mac OS? Thanks for your time and for answering my questions. K

    Kathy: The app generates the codes directly in the app on your device. You can use Keychain access to create password records in Keychain or secure notes, either one.

    How do I figure out which 2SA app works with which password manager, home security app or any other app, for that matter, that uses 2SA? Then you have to remember which 2SA app works with which one.

    Jacques: it would tell you that when you set up your account, usually with any links needed. Then it would remind you when it asks for the second factor. Often you have multiple choices, like I can use 1password to get my codes for Google instead of the Google Authenticator app.
