Paperwork, accounts and security basics

Around day one you will send documents, maybe open a bank account for your salary, and receive many new accounts: email, chat, code hosting and cloud consoles. Protect them from the start. Turn on two-factor authentication (2FA) everywhere, so a login needs your phone or a key as well as your password.

Use a password manager, never reuse a personal password, and lock your screen when you step away. New joiners are a favourite target for phishing, fake messages that try to trick you, because they do not yet know what normal internal messages look like.

If anyone urgently asks for codes, gift cards or approvals, check with that person directly. Only use personal devices for work if the company clearly allows it. The confidential data rules later in the roadmap build on this.
