1. It's made my account really secure, so much so that even I can't access it.Super bad experience! Can't sign in even when I approve on this authenticator! After uninstall, and reinstall, data was gone now I can't sign in to my account, any idea how can I sign in again? Email is taking too long to reply, and phone call requires 40 mins waiting time.... Please help....For setting up 2fa, it doesn't stay on the enter code screen after I look at the text message.

2. It is fast and easy to set up and does not require 6 digit codes- you just click on approve or deny button and nearly instantly your desktop think or swim platform will resume loading.Couldn't login to my account despite approving on my authenticator app.

3. Watched the app in progress till changing my first comment since it just good to have 2FA, quite happy to be able to say "it's working" especially after full user circle during targeted digital attack.It's a top security issue, after sending confirmation email.

4. Once you have downloaded the thinkorswim app and logged on to your account, if you had selected two factor authentication, then signing into the device with the authenticator will bind that device to your account.

5. Makes the Auth app unusable and 2fa is extremely important to me.quit working, lost registration of phone, reinstalled app, now cant get app to initialize.

6. It doesn't grant approval to the account even after clicking approve button.

7. After I reinstall the app, it doesn't even send approval confirmation when I trying to log in to this authenticator.

8. It's working might be a little annoying when changing mobile especially if old one is broken and phone lines are overloaded due to the season.

9. The TD Ameritrade system is probably more secure than SMS or email based 2FA.Thought reinstalling might make it work, it's totally a blank now.

10. But waiting for the call to go through was long (almost 15 mins in my case)Not working at all.

11. In short, I got locked out from this so called authenticator app, how ironic it is.Worked like a charm.
