WhatsApp (private messaging)

WhatsApp Chats: tap in quick messages, speak into the phone for a voice note and a lot more

WhatsApp Updates: Status lets you share text, photo, video and GIF updates that disappear after 24 hours with people when you both have each other saved as contacts. Channels are a one-way broadcast rather than a conversation

WhatsApp Calls: these work over the internet using data and can have up to 32 participants

WhatsApp Community: this is where you can organise multiple WhatsApp groups under one umbrella (to compete with Slack or Teams)

WhatsApp Menu: this is under the three dots top right. It is where the options New group, New broadcast, Linked devices, Starred messages and Settings are

WhatsApp linked devices: link up to four other devices – which will be signed out after 30 days of inactivity. Go to Menu ❯ Linked devices ❯ Link a device ❯ from the other device get a QR code and hold main phone over it

WhatsApp Two-step verification PIN: go to Settings ❯ Account ❯ Two-step verification ❯ Turn on, add a PIN you will remember easily ❯ enter and confirm your email address. This stops someone taking your SIM from your phone, putting it in another phone and signing into your WhatsApp as they would need this PIN (also if using it on a companion device the PIN is needed)

WhatsApp Settings: tap on the different options to add two-step verification (in Account) or set the Chat backup frequency to Daily (Chats)
