First of all, we take security really seriously. As for Two-Factor Auth, I have passed this to our developers and we'll get back to you with an update. :-)
Any updates for this topic?
We don't have a specific thing yet to announce but it's something we're discussing internally. Once we have something more concrete, we'll definitely let you know.
I would like to see this feature! Any updates?
This is something I would love to see.
I would be whiling to add some more sensitive information in note and will save me a lot of time.
You can already use two-step auth with Todoist.
1. Enable two-step auth for your Google account
2. Use your Google account to log in Todoist.
Anyway, +1 for native two-step auth support for those who don't have Google account.
I would like to see 2 factor authentication also. Toodledo has it.
