I'm sure this blogpost will be interesting to the two or three other people people in the world who are using Claude Code on Windows and want to have multiple accounts active :)

Keen to hear feedback and experiences 😀

Starting off the year with the uno reverse card 🤣🤣🤣

Kicking off our December meetup at @orcasec with some announcements from @JoshCGrossman.

(Including save the date, 18 May 2026, for #AppSecIL!!)

LONDON, BABY!

I'm bringing my course "Building a High-Value AppSec Scanning Programme" to London as part of @owasp's London training days, 23-24 February 2026.

As seen at OWASP Global conferences, @BlackHatEvents and @NDC_Conferences, don't miss your chance to attend!

CFTs for both @BlackHatEvents #BHUSA and @owasp Global AppSec EU (Vienna) are now open and close in early December!

Thinking of submitting? Check out my blog series for @BounceSecurity "So you want to train at Black Hat (or other conferences)?"
