OpenID on mobiles

So I run an openID enabled wiki site based on the excellent ikiwiki software called So how do they work with the mobile browsers on my ageing Nokia E65?

Cert check on Nokia Web browser

I have four browsers on my mobile and they all worked with
# Mozilla/4.0 (compatible; MSIE 6.0; Symbian OS; Series 60/0633.18.02; 9730) Opera 8.65 [en]
# Opera/8.01 (J2ME/MIDP; Opera Mini/3.1.7196/1684; en; U; ssr) – Opera Mini 3
# Opera/9.50 (J2ME/MIDP; Opera Mini/4.0.8462/20; U; en) – Opera Mini 4 beta
# SymbianOS/9.1; U; en-us) AppleWebKit/413 (KHTML, like Gecko) Safari/413 es65 – Nokia ‘Web’ Browser

1&4 incidentally asked for confirmation with the’s certificate.

I think there is an usability bug by having to type in one’s openid url, as none of the browsers seem to cache previous form fills for quick auto completion. Also it would be nice if I could have some sort of shortcut to submit the form like [Enter] does on my desktop browser.

For example my openid URL is, an insane 27 characters to key in. alone would be 19 characters and should also work. However you could use the open id delegate trick and hopefully you have access to a really short domain name. I use the trick on (see the HTML header source of this blog) and hence it’s 12 characters to type in…

Once logged in and the cookie session magic is are all there, OpenID is a dream. However I am wondering how the SIM or hardware of the mobile phone could perhaps skip the step of entering the password in and make it more secure. I assume the mobile browser needs some sort of interface to the SIM. I wonder how to realise this.

Do check out the screenshots I took of my testing session.
