Some applications use usernames and some don't. Some allow changing of usernames and some don't. I would like to know the pros and cons of allowing users to change their usernames and what are the rules that usually goes with it like minimum of 1 month before every change or a maximum of 5 changes.
Below are what I have come up so far.
- facebook - yes
- twitter - yes
- imgur - yes
- reddit - no
- google - yes
- youtube - yes (channels)
- deviantart - no
- instagram - yes
- pinterest - yes
- steam - no
I was hesitant to post my opinions on the matter as I would not like to influence the answers that I might get but since some have given out some downvotes below are my initial thoughts.
- more security on accounts
- people could hide from other people
- safer account management
- users could steal other usernames
- users could get away from misconduct
- users would have a hard time finding each other
- more complex database
What are the things you need to consider to allow your users to change their usernames? Like If its in the case of a social network, most of them do allow changing. When it comes to e-commerce sites most of them don't.
