Withdrawals are blocked for 24 hours after any of these changes:

you changed your password in the account;
you reset a forgotten password;
you turned off two-factor authentication;
you connected a new authenticator app instead of the old one;
Strade support unfroze your account (How do I freeze my account, and how is it unfrozen?).

Withdrawals are blocked for 72 hours after:

two-factor authentication was reset at your request (I lost access to my authenticator app);
a deleted account was restored at your request (How do I delete my account?).

Turning on two-factor authentication for the first time does not block withdrawals.

Sub-accounts are never blocked: they cannot withdraw (withdrawals are made only from the main account). When a sub-account changes its own password or two-factor authentication, its emails do not mention a block, and the withdrawals of the main account stay as they are.

Why: if someone took over your account and changed these settings, the pause gives you time to notice the security emails and react before funds can leave the account.

While the block is on, the withdrawal form shows Withdrawals are temporarily blocked until and the date and time. Withdrawals to other Strade users are blocked too. Deposits, trading, Swap and transfers between your own wallets and sub-accounts work as usual.

The block ends automatically at the time shown, and you get a Withdrawals unblocked notification and email. A new change during the block can extend it.

If you did not make the change, act at once: I think someone else has access to my account.

Stay safe: Strade support never asks for your password, 2FA codes or seed phrase.
