Basically I have some toy accounts for those sites, in names that read somewhat like Fortran variables, sans meaning. Currently using this thing called 33mail.

Basically I have some toy accounts for those sites, in names that read somewhat like Fortran variables, sans meaning. Currently using this thing called 33mail. Temp-mail works most times too, but 33mail forwards me the emails so I can even use forgot password option. On a relevant note, there are few websites that provide temporary phone numbers if you're from US/Canada, or in contexts US/Canada temporary phone number helps.
