         If put on the clipboard, it will be cleared in 45 seconds.
-    pass otp insert totp [--secret=key,-s key] [--algorithm alg,-a alg]
-                             [--period=seconds,-p seconds]
-                             [--digits=digits,-d digits] [--force,-f] pass-name
-        Insert new TOTP secret. Prompt before overwriting existing password
-        unless forced.
-    pass otp insert hotp [--secret=secret,-s secret]
-                             [--digits=digits,-d digits] [--force,-f]
-                             pass-name counter
-        Insert new HOTP secret with initial counter. Prompt before overwriting
-        existing password unless forced.
+
+    pass otp insert [--force,-f] [--echo,-e] [uri] pass-name
+        Insert a new OTP key URI. If one is not supplied, it will be read from
+        stdin. Optionally, echo the input. Prompt before overwriting existing
+        password unless forced.
+
     pass otp uri [--clip,-c] [--qrcode,-q] pass-name
-        Create a secret key URI suitable for importing into other TOTP clients.
-        Optionally, put it on the clipboard, or display a QR code.
+        Display the key URI stored in pass-name. Optionally, put it on the
+        clipboard, or display a QR code.
+
+    pass otp validate uri
+        Test if the given URI is a valid OTP key URI.

-## Example
+## Examples
 
 Insert a TOTP token:
 
 ```
-$ pass otp insert totp -s AAAAAAAAAAAAAAAAAAAAA totp-secret
-[master 4f9b989] Add given OTP secret for totp-secret to store.
- 1 file changed, 0 insertions(+), 0 deletions(-)
- create mode 100644 totp-secret.gpg
+$ pass otp insert otpauth://totp/totp-secret?secret=AAAAAAAAAAAAAAAA totp-secret
+```
 
+Have `pass-otp` prompt you for a token (avoids potential shell history leakage):
 
-$ pass show totp-secret
-otp_secret: AAAAAAAAAAAAAAAAAAAAA
-otp_type: totp
-otp_algorithm: sha1
-otp_period: 30
-otp_digits: 6
+```
+$ pass otp insert totp-secret
+```
+
+Pipe an `otpauth://` URI into a passfile:
+
+```
+$ cat totp-uri.txt | pass otp insert totp-secret
+```
+
+Use `[zbar](http://zbar.sourceforge.net/)` to decode a QR image into a passfile:
+
+```
+$ zbarimg -q --raw qrcode.png | pass otp insert totp-secret
 ```
 
 Generate a 2FA code using this token:
 
 ```
-$ pass otp show totp-secret
+$ pass otp totp-secret
 698816
 ```
 
+Display a QR code for an OTP token:
+
+```
+$ pass otp uri -q totp-secret

+## Migrating from pass-otp 0.1
+
+`pass-otp` has switched to storing OTP tokens in the
+standard
+[Key Uri Format](https://github.com/google/google-authenticator/wiki/Key-Uri-Format).
+You'll need to edit any saved tokens and change them to this format. For
+example:
+
+```
+$ pass edit totp-secret

+
+Old format:
+
+```
+otp_secret: AAAAAAAAAAAAAAAA

+otp_digits: 6
