What a Master ID is

Your Master ID is your account in Tacq. It looks like TacqXXXXXXXX, is generated on your device, and isn’t tied to a phone or email.

• Master ID + password is your login. You use them to sign in, including on another device.
• Nickname is a separate thing: a visible name you set yourself and can change; it can differ in each group.

Keep your Master ID and password somewhere safe — see A password can't be recovered.
