#Profile addition to redefine cd as a proxy for push location (and cd- for Pop). 
#    cd ...     is transformed into into cd ..\.. (extra dot is an extra level), 
#    cd ^       is transformed into cd <<script i.e. profile>> directory
#    cd \*doc   is transformed into cd \*\Doc*\
#    cd =       is transformed into an item from the stack. = is the first each extra = goes one deeper in the stack
#    cd -       will not tab expand but will pop an item from the location stack. 3 or more - will do an extra pop.

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
