TOTP token is not generated if spaces in secret

The TOTP token management algorithm can be improved to ignore spaces in the secret.

sample :
`key=lgdg shhdb bebxjs djenx
`This won't work

`key=lgdgshhdbbebxjsdjenx
`Edited, removed the spaces, it will work.

Locate the TOTP token generation entry point and reproduce the reported difference between spaced and unspaced secrets. Check the existing behavior for the sample secret, then verify that both forms generate the same token after the change.
