The app is asking for a password and I don't know which one to give it
Password advice
There are two password interactions with the app.
You will need your account password to log in to the app, which is the same as your 'My Dyson' account password if you are registered on the website.
The other value you need is the WiFi password to connect to the purifier. The serial number and WiFi information can be found in the following locations:
On the front of the instruction manual.
On the remote control packaging.
On a removable sticker on the front of the purifier.
On your purifier, located underneath the filter.
The purifiers password is made up of numbers and lower case letters only, so '0' is definitely the number zero. The number '1' and the letter 'l' (L) may look similar, as may the letters 'j' (J) and 'i' (I).
