When in a web field that needs an email address you should see ‘Hide My Email’ just above the keyboard.
Tap the field and then tap ‘Continue’.
Add a note to the email to describe it and then tap ‘Use’.
To send an email from the email address created above simply tap the ‘From…’ field when composing an email and then ‘Hide My Email’.
You can now choose the one you want to use.
Sometimes you just need to know how to use a feature or do something new without loads of adverts or pop-ups getting in the way. I hope this tip was useful to you.
