Under notifications there will be a reminder to back up credentials once you receive sats,  click this it will take you to auth... otherwise there should be an auth link in the hamburger menu

You're not the first to point out this is unintuitive... trying to design something cleaner... 

 actually looks like there was a nav regression... just merged a fix, will have a build shortly 

 Thanks! 

 I can now see the auth.

However, I can't login with existing nsec to sanctum.

Is that suppose to work? 

 It's supposed to but is also very new, what are you experiencing? 

 I select free, paste nsec and click continue.

It does nothing. Only logs "continue..." in console (no errors or anything).

btw. whe you paste nsec and then click subscription option it will erase the nsec.

 Thanks, investigating...
