## Description
When using 2fa enabled authentication on direct templates we run into an
issue where a 2fa token has been attached to a field but it's submitted
at a later point.
To better facilitate this we have introduced the ability to have a
window of valid tokens.
This won't affect other signing methods since tokens are verified
immediately after they're entered.
## Related Issue
N/A
## Changes Made
- Updated our validate2FAToken method to use a window based approach
rather than the default verify method.
## Testing Performed
- Created a series of tokens and tested upon different intervals and
windows to confirm functionality works as expected.
