For me its realistically 30 secs to a minute. I have to look for phone, load up authy, then enter the code. I think most on here dont have an issue with 2FA, but having to redo it every 30 days will likely drop off activity, as I might be too busy to grab the phone to make that ocuk post, so would just browse as guest instead. Will see as I do like the ocuk community. Ironic that forums are implementing this but still no 2fa at my bank like they stuck in the stone age.
