generateURI doesn't work with Google authenticator

[ckr]

It looks like google doesn't like digits, digest and interval in the provisioning url.

I just tried to generate a TOTP including digits, digest and interval parameters and it works fine for me.

Please, could you try this one, it is correctly loaded on Google Authenticator (v2.49) and codes generated are correct:
otpauth://totp/Bar%3AFoo?algorithm=sha1&digits=6&issuer=Bar&period=30&secret=KRUGS4ZANFZSA3LZEBZWKY3SMV2A

[ckr]

Still doesn't scan on google authenticator for ios

OK my tests are based on Google Authenticator for Android.

If the following code is correctly loaded on your app, I will update my library.
I think I will remove parameters if algorithm=sha1, period=30 and digits=6.
otpauth://totp/Bar%3AFoo?issuer=Bar&secret=KRUGS4ZANFZSA3LZEBZWKY3SMV2A

[ckr]

Nope it doesn't work. If i remove the extra characters at the end it works.

Thank.
I am sorry I did not notice the trailing "=" in my examples.
Please could you try again the first barcode?

I have also updated my library. It should work fine now (use the last dev-master release).
If it is correctly loaded, I will tag it as stable soon.

[ckr]

The second example works not the first. Thanks for the quick reply. Wouldn't not returning the algorithm=sha1, period=30 and digits=6 break other apps like FreeOTP? Maybe a second function generate google uri would be better?

[Spomky]

You are right, it could break other apps.
I added a parameter on method getProvisioningUri: a boolean:

• if true (default), $totp->getProvisioningUri(); (or $totp->getProvisioningUri(true);) produces URIs compatible with Google Authenticator by default.
• if false, $totp->getProvisioningUri(false); will keep all parameters for compatibility with other apps

Hi, I am working with @ckr on this. We have tested and it now works fine. Thank you for the quick fix.

Will this get auto-updated on Packagist?

Thanks again!

Hi,
I just release v4.0.2. It is already available via Packagist.

Thank for the report.
