2FA - does it work without limit?

[sadden3194]

Hi all!

a little question. I am using acme.sh on my synology as a docker container.
I have a user for this, which have 2FA enabled.

For this part I found these lines in the wiki:

Note that if the user entered for SYNO_Username has enabled two-factor authentication (2FA), the login will fail and the error states that user/password is wrong, even if both are correct. To fix this, simply follow the steps described at the [Synology DSM deployhook](https://github.com/acmesh-official/acme.sh/wiki/deployhooks#20-deploy-the-certificate-to-synology-dsm) wiki page - in short: log into your DSM via its website, making sure you've ticked Remember this device when asked for your OTP, get the did cookie's value and set the environment variable:

export SYNO_DID='YOUR VALUE'

Have the did cookie's value a limit time?
If yes I have to do this process every x days / month to get a new did?
