It’s a very good policy for convenience, and having seen this from the customer support side – I think this should be implemented everywhere.
You can write the password like this: “ abc def ghi ” and copy it to a piece of paper, or copy and paste.
It’s simply easier to strip all spaces than to keep telling everyone:
- “Make sure you aren’t copying and pasting any white space characters”
- “Type in the password manually, don’t copy and paste it”
Which is usually an answer to the question:
- “My password isn’t working, even though I copied it exactly from the email you sent to me”
