I'm sorry, but I'm a bit confused. I still see all 3 of those items in our "production" install of 17.0.6821 and they appear to be working fine. You're saying they're completely removed from webmail? We haven't' done anything to remove any of those features from the last release to this one, so I'm not sure what's going on.

I am sorry. I did not gone deep into it.

Let me elaborate. I believe I manage to find the steps to reproduce this error where the 2-Step Authentication is no longer available:

- Login in the Webmail with an account that has 2-step authentication enabled
- Enter your 2 step authentication token verification.
- Logout from the account 

this shows that the 2 step authentication is working

To create the problem, you need to login as the Systems Administrator as follows:

- Now login using the System Administrator using a separate browser tab
- Impersonate the same account whom you use to login earlier.
- Go to the User Settings->Profile
- FIrst you will release the Nickname, Spouse Name, Assistant Name and other fields are missing
- Try to save anything on the Profile using the Impersonated accounts.
- Next go to the Domain Setting->Accounts
- Select the same user
- You will realise that you cannot view the account passwords, such as the IMAP/SMTP/POP3 password and other password.

Next :

- Login using the same account and email password
- There is no google authentication verification.

I hope I can make myself clearer when I say 2-Step Authentication are no longer available

As for the second problem highlighted, you can easily go to the Profile of the user and see that the newly added fields are no longer available in the new version. This is also mentioned in my steps earlier.

Another bug mentioned are the Show Password are gone if you follow the steps above. 

To enable back the 2 step authentication:

- Go to the Setting->Account
- Disable the 2 step authentication
- Enable it again
- Fortunately, the IMAP/POP/SMTP and other password remains the same. If not, the user will scream at us each time they have to disable and enable it due to whatever reasons.

Thanks for the reports. I've reported the following issues to the development team to be resolved: 

 

Regarding Show Password... are you logged in with the primary Administrator account or a secondary Administrator account? The primary Admin should always have the ability to view passwords while impersonating, but secondary Administrators need the account setting, "Allow shows passwords while impersonating" in order to see that option. 

We realise that impersonating an account does not allow the Photo of the account profile to be saved too.
