[pass] gpg: decryption failed: No secret key

[Daniel Sousa]

I am trying to use pass, but I always get the same error

➜  ~  pass init ACBBA601 
Password store initialized for ACBBA601
➜  ~  pass generate foo 10
The generated password for foo is:
D-afY9}7:T
➜  ~  pass foo
gpg: decryption failed: No secret key

gpg2 has the key:
➜  ~  gpg2 --list-keys
(...)
pub   rsa2048/ACBBA601 2016-04-03 [SC]
uid         [ultimate] Daniel Sousa (Passwords) <passwords at daniel.sousa.me>
sub   rsa2048/E670104C 2016-04-03 [E]

Can someone help me find the problem?
