I registered and in the panel, it says that the account expires in 3 months, what will happen in 3 months?

Your account will not expire within the specified period. However, it is required to log in at least once every 3 months through the hosting account panel, SSH, or SFTP (not to be confused with FTP).

a month later

Good morning
I saw this on the devilweb panel: Expiration date: Oct. 19, 2033, 3:04 p.m.
This means that it is in 10 years... Is this normal?
And does this correspond to the duration of 90 days without logging in?

Do not overapply submissions, as per the link quoted in the response above your answer: 'The expiration date is increased at every login into your account (DevilWEB panel and SSH/SFTP count; FTP/FTPS don't because FTP accounts are virtual, created by the user).'"

So currently, this value doesn't mean anything.
